Hey guys,
   I really appreciate all the help.  I made some changes to the
cygload.cc program by adding a changing the main method into a
init_cygwin_lib method and building it as a shared library.  My C#
application now calls this init_cygwin_lib, but when it does the
application just mysteriously exits when the
cygwin1.dll:cygwin_dll_init() is called.  I suspect the funky stack
pointer logic is corrupting some memory:

Connecting to cygwin...
Warning!  Stack base is 0xdb0000.  padding ends at 0xdaf844.  Delta is
1980.  St
ack variables could be overwritten!
Loading cygwin1.dll...
Initializing cygwin...
Before cygwin_dll_init call.

Is there anything else I can try?  Thanks!

Regards,
Sammy
