I have to admit that I never had enough energy to look at yet another 
POSIX-like environment on Windows, but perhaps you're right and I should do 
this...

:-) What I'm basically arguing for is that even people who choose to ignore 
POSIX/autotools might be better off using feature-based #ifdefs most of the 
time: You can isolate the platform-based #ifdefs into a single place to 
#define the needed feature-based one, and use only the latter in the rest of 
your code. And for autoconf projects on a non-POSIX platform this boils down 
to providing a config.h.in filled out by hand, which is quite easy if you 
know your platform. In any case: 99% of the code should be free of 
platform-based #ifdefs. Perhaps I should make this clearer on my page...
