I have recently installed the new net release of cygwin (and upgraded to version
1.1.1 of cygwin1.dll at the same time).  A package which compiled as a dll
successfully under b20.1, with Mumit Khan's mingw32 port of gcc and g77 now
fails, with the following errors.  Can someone on the list give me a hint about
what might be going on?
The relevant output from make is:

------- Building odesolve.dll from odesolve.a --------
echo LIBRARY odesolve > odesolve.def
echo EXPORTS >> odesolve.def
nm odesolve.a > Defs
sed -n "/^........ [BCDRT] _/s/^........ [BCDRT] _/ /p" Defs >> odesolve.def

Thanks for any help you can give me!
