Doesn't seem to help. Now I get a bunch of _imp___ctype not found errors
when trying to link cygwin1.dll. I think the problem is related to this:

/src/newlib/libc/include/sys/config.h has this little snippet:

#if defined(__CYGWIN32__) || defined(__CYGWIN__)
#if defined(__INSIDE_CYGWIN__) || defined(_COMPILING_NEWLIB)
#define __IMPORT
#else
#define __IMPORT __declspec(dllimport)
#endif
#endif

/src/newlib/libc/include/ctype.h defines ctype:

extern  __IMPORT _CONST char    _ctype_[];

So it's important that __IMPORT get defined correctly -- that is, that
__INSIDE_CYGWIN__ is defined before anything in newlib/libc/include gets
included. 

winsup.h has the following:

#ifdef HAVE_CONFIG_H
# include "config.h"
#endif

#define __INSIDE_CYGWIN__

(Don't let it throw you, that's a different config.h file). The problem
is, winsup.h defines __INSIDE_CYGWIN__, but most of the .cc files in
winsup include stuff like <errno.h> and <stdlib.h> *before* winsup.h.
These <include files> get resolved to the newlib/libc/include directory,
and poof: libc/include/sys/config.h gets included but __INSIDE_CYGWIN__
hasn't been defined yet.

I don't know what the right way to fix this is. Help?
