MinGW (gcc -mno-cygwin) Update

Well, the good news is that I finally succeeded in getting XEmacs 21.4.1 to build with MinGW (-mno-cygwin). I tried to use pdump but xemacs.exe kept crashing during initialization. If somebody with more knowledge of the pdump code wants to give me pointers on how to debug the problem, I'll try pdump again. I finally hacked unexcw.c to compile again and finally succeeded in producing a runable xemacs.exe. Long term, we should probably try to use unexnt.c for the MinGW port instead of unexcw.c, but I didn't have time today to try to get it to work. Below is a diff between my workspace and the 21.4 branch in CVS. This is not a final patch, by any means, and is only included for people to comment on.
