[M3devel] compile problem on LINUXLIBC6

[Mika Nystrom]

In order to build m3cc, all I had to do was remove the declaration for
basename() from /usr/cvs/cm3/m3-sys/m3cc/gcc-4.5/include/libiberty.h

I find it a bit odd since my system uses gcc 4.5.0 but am not quite sure
what should be done about it.
