egcs-1.1.1 for DJGPP is beta practically only due to problems with exceptions.
DJGPP port of gcc-2.8.1 is more stable with exceptions so we are not yet 
ready to replace it (maybe with egcs-1.1.2 if such will be released sometimes).

There were no serious problems to build pgcc-1.1.1 for DJGPP. The script I used
to modify egcs-1.1.1 sources to build them for DJGPP almost works also for PGCC
(only some small corrections needed). See gnu/egcs-1.11/contrib/egcs-patch.sh
in egcs111s.zip for details.

The problem is that at first I was not satisfied with pgcc-1.1.1 I built for DJGPP:
	-  libstdc++.a built with options '-mpentium -O6' failed tests (crashes in tests
		 for targets check-target-libio and check-target-libstdc++ but I didn't test
               further)
       -  BYTE Benchmarks compiled with same options crashes in some tests so
               I didn't suceed to do good comparisson (And I didn't want to mess 
               much about this)

As the result I'm not using pgcc-1.1.1 for DOS now.
