The sigaltstack declaration should only appear when this platform check fails:

 config_cmake/CMakeLists.txt:CHECK_DECL_EXISTS(sigaltstack HAVE_DECL_SIGALTSTACK)

Please look at CMakeFiles/CMakeError.log for mention of HAVE_DECL_SIGALTSTACK to see why it doesn't think the system declares the function.

The struct member names are defined here:

 /usr/include/ppc/_structs.h

and switch based on how __DARWIN_UNIX03 is defined here:

 /usr/include/sys/cdefs.h

More investigation is needed as to why the names do not match those expected by the source.

As announced here:

 [ANNOUNCE] GCC-XML maintenance moving to Github
 http://thread.gmane.org/gmane.comp.compilers.gccxml/731 [^]
 http://public.kitware.com/pipermail/gccxml/2015-March/003206.html [^]

gccxml will no longer be developed by its original author, who will instead focus on CastXML:

The original GCC-XML issue tracker is now closed. In order to facilitate ongoing maintenance by community participants, issues will now be tracked on the Github repository page:
