gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-12ubuntu1)

asm() doesn't seem to work with -std=c99. It's a bad idea in my opinion, since the standard actually suggests that compilers support an asm() keyword, but it isn't mandatory. 

Try -std=gnu99

-std=

Determine the language standard. This option is currently only supported when compiling C or C ++ .

The compiler can accept several base standards, such as c89 or c++98, and GNU dialects of those standards, such as gnu89 or gnu++98. By specifying a base standard, the compiler will accept all programs following that standard and those using GNU extensions that do not contradict it. For example, -std=c89 turns off certain features of GCC that are incompatible with ISO C90, such as the "asm" and "typeof" keywords, but not other GNU extensions that do not have a meaning in ISO C90, such as omitting the middle term of a "?:" expression. On the other hand, by specifying a GNU dialect of a standard, all features the compiler support are enabled, even when those features change the meaning of the base standard and some strict-conforming programs may be rejected. The particular standard is used by -pedantic to identify which features are GNU extensions given that version of the standard. For example -std=gnu89 -pedantic would warn about C ++ style // comments, while -std=gnu99 -pedantic would not.

A value for this option must be provided; possible values are

c89

iso9899:1990

Support all ISO C90 programs (certain GNU extensions that conflict with ISO C90 are disabled). Same as -ansi for C code.

iso9899:199409

ISO C90 as modified in amendment 1.

c99

c9x

iso9899:1999

iso9899:199x

ISO C99. Note that this standard is not yet fully supported; see <http://gcc.gnu.org/gcc-4.4/c99status.html> for more information. The names c9x and iso9899:199x are deprecated.

gnu89

GNU dialect of ISO C90 (including some C99 features). This is the default for C code.

gnu99

gnu9x

GNU dialect of ISO C99. When ISO C99 is fully implemented in GCC , this will become the default. The name gnu9x is deprecated.

c++98

The 1998 ISO C ++ standard plus amendments. Same as -ansi for C ++ code.

gnu++98

GNU dialect of -std=c++98. This is the default for C ++ code.

c++0x

The working draft of the upcoming ISO C ++ 0x standard. This option enables experimental features that are likely to be included in C ++ 0x. The working draft is constantly changing, and any feature that is enabled by this flag may be removed from future versions of GCC if it is not part of the C ++ 0x standard.

gnu++0x

GNU dialect of -std=c++0x. This option enables experimental features that may be removed in future versions of GCC . 

Host Specifications

A "host list" tells distcc which machines to use for compilation. In order, distcc looks in the $DISTCC_HOSTS environment variable, the user's $DISTCC_DIR/hosts file, and the system-wide host file. If no host list can be found, distcc emits a warning and compiles locally.

The host list is a simple whitespace separated list of host specifications. The simplest and most common form is a host names, such as

localhost red green blue

distcc prefers hosts towards the start of the list, so machines should be listed in descending order of speed. In particular, when only a single compilation can be run (such as from a configure script), the first machine listed is used (but see --randomize below). 

--randomize

Randomize the order of the host list before execution.

$ cat /etc/distcc/hosts

# As described in the distcc manpage, this file can be used for a global

# list of available distcc hosts.

#

# The list from this file will only be used, if neither the

# environment variable DISTCC_HOSTS, nor the file $HOME/.distcc/hosts

# contains a valid list of hosts.

#

# Add a list of hostnames in one line, seperated by spaces, here.

-i, --ip-address

Display the IP address(es) of the host. Note that this works only if the host name can be resolved. Avoid using this option; use hostname --all-ip-addresses instead. 

-I, --all-ip-addresses

Display all network addresses of the host. This option enumerates all configured addresses on all network interfaces. The loopback interface and IPv6 link-local addresses are omitted. Contrary to option -i, this option does not depend on name resolution. Do not make any assumptions about the order of the output.

--enable-c99

The long long type was introduced in C99, along with many other functions for wide characters, and math classification macros, etc. If enabled, all C99 functions not specified by the C++ standard will be put into namespace __gnu_cxx, and then all these names will be injected into namespace std, so that C99 functions can be used "as if" they were in the C++ standard (as they will eventually be in some future revision of the standard, without a doubt). By default, C99 support is on, assuming the configure probes find all the necessary functions and bits necessary. This option can change the library ABI.
