Where does it say that in the GPL? Why are people so misinformed about
this? The GPL isn't really that long..

3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

In this case, the "source code" includes not only his modified version
of asterisk, but also the source code to whatever parts of cygwin he is
distributing or linking to, since cygwin is also GPL.
It would also include the source code (or maybe only the object code?)
for the cygwin development environment, since the cygwin compiler is not
"normally distributed [..] witht he major components [..] of the
operating system [Windows] on which the executable runs".
But, all this is not really that onerous: All he needs to do is:
1) cd <directory with his source>; tar cvzf
/tmp/asterisk-win32-some-version.tar.gz source-dir; scp
/tmp/asterisk-win32-some-version.tar.gz webserver:place
2) wget http://www.cygwin.com/<cygwin-stuff>; scp -r <cygwin-stuff>
webserver:place.
