[RFC]: Move __CYGWIN__ hack to config/<arch>/xm-cygwin.h
Thu Mar 1 18:21:00 GMT 2001
I found some code in defs.h that defines __CYGWIN__ if __CYGWIN32__ is
defined (if it is not already defined). While I admit that defs.h has
it's fair share of hacks they are more general (for the most part, they
add definitions missing from older UN*X systems (SEEK_SET, STDIN_FILENO,
etc.). IMO, this code belongs in a cygwin host header file.
The enclosed patch moves it from defs.h to config/i386/xm-cygwin.h and
config/powerpc/xm-cygwin.h. It seems to me there is enough duplication
in those two headers that a common config/xm-cygwin.h header is justified,
but I'll leave that to cygwin hackers to deal with.

* defs.h (__CYGWIN__): Moved conditional which defines __CYGWIN__
if __CYGWIN32__ is set from here.
* config/i386/xm-cygwin.h: To here.
* config/powerpc/xm-cygwin.h: To here.
