Re: -m31 rejected when building libgcc for cross compiler for s390 (31 bit) gcc 4.6.0
Thanks, Ian. That brought me further, but still no cigar. Does the
following ring a bell?
/usr/ports/gcc390/build460/./gcc/xgcc

compilation terminated.
So I looked for string.h in the source:
u@ubuntu:/usr/src/gcc-4.6.0$ find . -name 'string.h'
./libssp/ssp/string.h
./fixincludes/tests/base/string.h
./libstdc++-v3/include/c_compatibility/string.h
