- _mingw.h: Don't define __attribute__ to nothing -- this is only good for creating bugs.

- sect_attribs.h: Define _CRTALLOC for msvc. Enable #pragma section and add missing .tls and .tls$ZZZ.
- mingw runtime: Only use __attribute__((weak)) for gcc.
- freeldr: Use #pragma pack instead of __attribute__((packed)).
- kernel32: Only alias __cxa_pure_virtual to _purecall for gcc.
