If I understand you correctly, then it's not so difficult; I've done it
myself with bmp, gedit, gthumb, liferea, and xmms.

I don't know Asterisk, but it doesn't appear to use autotools; this
makes things more difficult, especially if you want to make a portable
patch.

First, make sure that the asterisk executable is built *first*; you may
need to precede '.' to the SUBDIRS variable (i.e. SUBDIRS = . subdir1
subdir2 etc.)

Add the following to the asterisk executable's LDFLAGS:
'-Wl,--export-all-symbols,--out-implib,libasterisk.dll.a'

Then, add the following to all the modules LDFLAGS, specifying the
correct location: '-Wl,/path/to/libasterisk.dll.a'.

Of course, make sure that all requisite link libraries are specified in
LIBS for both the executable and the modules.

You'll still need to find some way of making all this dependent on
Cygwin in the Makefiles in order to make this portable.
