Yep.

I did a "strace -f -ff -o blub axiom" and the lines you're probably interested
in are
execve("/usr/bin/gcc", ["gcc", "-c", "-Wall", "-DVOL=volatile",
"-fsigned-char", "-Wno-unused-but-set-variable", "-pipe", "-I../h", "-O3",
"-fomit-frame-pointer", "-c", "/tmp/gazonk2.c", "-o", "/tmp/gazonk2.o", "-w"],
[/* 47 vars */]) = 0
and
execve("/usr/bin/gcc-4.7.real", ["/usr/bin/gcc-4.7.real", "-fstack-protector",
"--param=ssp-buffer-size=4", "-fPIE", "-D_FORTIFY_SOURCE=2", "-Wformat",
"-Wformat-security", "-Werror=format-security", "-c", "-Wall",
"-DVOL=volatile", "-fsigned-char", "-Wno-unused-but-set-variable", "-pipe",
"-I../h", "-O3", ...], [/* 47 vars */]) = 0
Thank you very much.
Regards,
Edi
