GCC-the-platform ships its own system headers (and libraries), and thus
is very sensitive about the target platform.
On the other hand, GCC-the-compiler is quite a bit more flexible. I
don't think it would be such a huge effort to make it accept some MSVC-
specific constructs.
Also, the emulation code in Synopsis merely simulates native compilers
by providing predefined macros and include search paths so its own preprocessor
can be used with system headers (from the emulated compiler). A similar
approach could work for GCC, too. It's just a matter of some programming. :-)
