According to Corinna Vinschen on 6/20/2007 8:53 AM:

Actually, more like I did for fopencookie.  fmemopen doesn't need to worry
about growth, and provided that realloc is intelligent, open_memstream
shouldn't be too slow, either.

Also, psignal and psiginfo seem pretty easy to implement.

Here's a first patch to the list of functions, by the way, along with
recent newlib additions:

2007-06-20  Eric Blake  <ebb9@byu.net>

	* cygwin.din: Export exp10, exp10f, pow10, pow10f, strcasestr,
	funopen, fopencookie.
	* include/cygwin/version.h: Bump API minor number.
	* posix.sgml: Minor improvements.

Don't work too hard, make some time for fun as well!
