Description Danny Smith 2007-10-30 00:29:56 UTC 
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 ?

Because this is an old testcase.
