[Dev-C++] MingWin or Cygwin

[Maya <Esc...@ne...>]

I am developing a program that gets compiled under two platformes, Linux 
and Windows. In MSW I use Dev-Cpp, which in turn uses MingWin, a minimal 
GCC, but in Linux I use GCC; which is the complete version of GCC. Now 
my problems is that there are certain C functions that are incompatible 
with the two versions of the GCC package, one of them is 'mkdir'. In 
MingWin the declaration is ' int mkdir(const char*)' but in UNIX it is 
'int mkdir(const char* , int). What can I do to let know the compiler 
that if it is MingWin it should use one incarnation of the function and 
visa versa?
Example:
#ifdef MINGWIN
 ... use mkdir("file.dat")
#endif
#ifdef CYWIN
 ... use mkdir("file.data", 0);
#endif
#ifdef __GCC__
...etc., etc.
#endif
