redefinition of typedef ‘NIM_STATIC_ASSERT_AUX’ in x32

[h4cnull]

I try to use musl-gcc build a 32bit file。
system: centos6.8 i386
command: nim --gcc.exe:musl-gcc --gcc.linkerexe:musl-gcc --passL:-static -d:release -d:danger -d:strip --opt:size c xxx.nim
error out:

@h4cnull PR welcome

I back up lib/nimbash.h and add comment these lines，error fixed。
274 //#else
275 //#define NIM_STATIC_ASSERT(x, msg) typedef int NIM_STATIC_ASSERT_AUX[(x) ? 1 : -1];

323 //NIM_STATIC_ASSERT(sizeof(NIM_BOOL) == 1, ""); // check whether really needed
542 //NIM_STATIC_ASSERT(sizeof(NI) == sizeof(void*) && NIM_INTBITS == sizeof(NI)*8 , "");

I'm able to reproduce the issue by using gcc 4.1 or 4.2:

./bin/nim c --gcc.exe:gcc-4.2 koch.nim
