[Bug bootstrap/40702] New: lto-elf.c fails to compile on Solaris

[ro at gcc dot gnu dot org]

Trying to build the lto branch as of 20090709 on Solaris (both SPARC and x86)
fails compiling lto-elf.c:

cc1: warnings being treated as errors
In file included from /vol/gcc/src/gcc-lto/gcc/lto/lto-elf.c:21:0:
/vol/gcc/include/libelf/gelf.h:102:1: error: function declaration isn't a
prototype

This happens because for some reason __STDC__ isn't defined at all (as revealed
by rebuilding with -g3 -save-temps), so libelf/libelf.h defines __P() as empty.
I've hacked around this by adding || defined(__sun) to the first __P definition
in libelf/gelf.h and libelf/libelf.h, but this needs to be properly
investigated.
