Ouch! This IMHO warrants a bug report to Cygwin maintainers.

That's true, except that _P is used in many libraries' header files to
allow prototypes in ANSI compilers without breaking non-ANSI ones.
Okay, if this is the case, please make the #undef _P thing conditioned
on Cygwin. That would at least limit the effect of the change to the
Cygwin build. I'd also suggest a comment there explaining why is this
done, which mentions the use of _P in ctype.h macros.
