Re: Build problem and problem with region in 21.5 under Cygwin.

I just made my first pass at building 21.5 on Cygwin. So far, I've found a (minor) problem with the build and a runtime problem that I haven't been able to figure out. The build problem was fairly simple. There was a conflict between some typedefs in src/lisp.h and /usr/include/cygwin/types.h. The conflicting lines are typedef int intptr_t; typedef unsigned int uintptr_t; at around line 803 in src/lisp.h. These are typedef'd differently in /usr/include/cygwin/types.h: typedef long intptr_t; typedef unsigned long uintptr_t; I got around the problem by surrounding the conflicting typedefs in src/lisp.h with #if !defined(__CYGWIN__) ... #endif
