Being a definite newbie in this area I'm now wondering about several cross
compilers I've built for a product we have.

I'm targeting i386-pc-solaris2.6, sparc-sun-solaris2.5.1,
powerpc-ibm-aix4.2.1.0 and i586-pc-linux-gnu.  Because I copied the libs
and headers from the original hosts and I'm using C only (no C++) I have
assumed that the backwards compatibility problems Kai described will not
affect me, but is that safe to assume?  I did have to build glibc to build
GCC (3.2), but I have been under the impression that this was an internal
compiler thing and wouldn't affect output binaries...?   

In summary I'm asking: If I use the hosts original libs and headers, and
only use C (no C++) am I still going to be affected by backwards
compatibility problems with the compiler/glibc and thus should rather be
using GCC 2.95 with an older glibc?

Thanks,

-Nathan
