testsuite gcc.c-torture/execute/multi-ix.c calls __builtin_bzero;
At -O0, this gets expanded to a libcall to non-ISO function bzero
mingw32 does not have a library function bzero.. Hence:
spawn /develop/svn/trunk/build/gcc/xgcc -B/develop/svn/trunk/build/gcc/
/develop/svn/trunk/src/gcc/testsuite/gcc.c-torture/execute/multi-ix.c -w -O0
-fno-show-column -lm -o /develop/svn/trunk/build/gcc/testsuite/gcc/multi-ix.x0
c:\tmp/ccsxRYXw.o:multi-ix.c:(.text+0x9a3): undefined reference to `_bzero'
Why not use ___builtin_memset in the testcase instead of poisoned name ?
