I'd like to inject a different idea:
In a larger project we did over here, I solved this problem as follows:

- All programming was done in accordance with posix,
  as far as the items were defined in posix.
- all posix procedures used were listed and placed in
  posix.h and posix.c files, which contained mostly comments.
  The posix.h also included all posix headers.
- all machines which didn't have a posix implementation,
  or used variations thereof, had their own .h anc .c
- upon calling make, make would determine the last architecture
  used. If the last and current differed, it would isue a
  make clean, then relink the .h and .c from the appropriate
  architecture to system.h and system.c, then make.

This way we could keep all system dependent stuff out of the code (no  
#ifdef ...) and porting to a new architecture was quite easy, as we could  
normally find something close to start with, then modify the .h and .c  
files.

I do realize that this would be a huge change, but ...
Would I do it? Yep, I would. But not within two weeks.
