Why: simply I think it's better way how to specify stack size rather than 
separate stubeditting executable (I can add corresponding
option to LDFLAGS without need to add some else DJGPP related
stuff to Makefile).

I also haven't seen many such examples where such option should be needed. Earlier I 
stubeditted part of gcc-2.95.X binaries to have 1.5Mb stack. My current binaries of gcc-3.0 
prerelease have the default stack
size and I havent't run into trouble

One example where I met need for similar options was running tests of GSL-0.7 (GNU 
Scientific library) rather long time ago (one example required about 1.5Mb stack size). 
Haven't tried with GSL-0.8 yet.

PS. Here is output I got from one test compilation. As You can see this
      option doesn't go anywhere else (not that I have patched stubedit
	to have option -x to force replacing extension with .exe)

Command: gcc -v -O2 x.cc -stack=1024k -lstdcxx -o x.exe
