OK, for now I'm just using whatever combination of __WIN32__ and
__CYGWIN__ that seems appropriate for the features I want. But maybe
we should define some more specific preprocessor variables in config.h
based on these symbols. Something like
// Define if the system has C:\foo\bar file names
#if defined (__WIN32__) || defined (__CYGWIN__)
#define HAVE_WINDOWS_FILESYSTEM 1
#endif
// Define if we expect to have <windows.h>, Sleep, etc.
#if defined (__WIN32__) || ! (defined (__CYGWIN__) || ...)
#define USE_WINDOWS_API 1
#endif
might be better since these variable names describe features rather
than system names.
