[C2M] Fail to parse GLIBC bits/wchar.h

[edubart]

With glibc 2.30 (under ArchLinux), the following fails to parse:

#include <wchar.h>
int main(int argc, char *argv[]){return 0;}

Outputs:

/usr/include/bits/wchar.h:35:8: wrong preprocessor expression
/usr/include/bits/wchar.h:43:8: wrong preprocessor expression

The culprit is this odd line
https://github.com/bminor/glibc/blob/glibc-2.30/bits/wchar.h#L35

PS: I've run into the issue while trying out to run with c2m a game made with SDL2. By commenting the lines in wchar.h I was able to run! So this was the only parsing issue.

Support of wide chars is not implemented yet in the C-to-MIR compiler (neither in preprocessor, nor in in the rest of the compiler). But I have plans to implement full C11 standard w/o optional variable arrays, complex numbers and atomic data (although it might be necessary to implement for my purposes: CRuby JIT).

Currently, wide-chars and full x86-64 call ABI (x86-64 call ABI permits to pass structures partially or fully though registers) are big parts not implemented yet.

It looks like <wchar.h> can be included with no issues nowadays and this issue was more about the inability to parse code that included it, so I'm closing the issue.
