Hello Sergey,
I have a portability header and I could do what you suggest however the problem 
I describe would occur whether I do it your way or by 'gcc ... -U_WIN32 ...'. 
 In fact the way you suggest is the way I initially did it.  It took a bit of 
fiddling to isolate the problem area to the unistd.h and __MS_types__ :-).
Thanks for your suggestion anyway.
I just thought I return some of the favours by sharing a solution to a possible 
problem someone might have one day :-)
