I didn't have any crashes (or other problems) with egcs-1.1 compiled using
slightly patched DJDEV202 except of one example that crashes cc1plus
also under Linux (SIGSEGV). egcs-1.0.3 compiles it (also under Linux).
So this problem is not DJGPP specific. As I mentioned in 
redame.djgpp I had to patch 2 things in DJDEV202:

bug in realloc(): caused crashes in cc1.exe in some sources (maybe also
     somewhere else, but I didn't study this more)

ENFILE instead of ENMFILE: caused problem when COMPILER_PATH were specified
in DJGPP.ENV as in DJDEV202

I didn't met any special problems so I think we should try to release it
as it is (compiled using DJDEV202). Only think we should change is to
modify gcc-e11b.zip to have exceptions support with DJDEV201 and
to have replacement of math.h in compiler version specific directory
similary as we had with gcc-2.8.1.

So I suggest that we can release it as it is without rebuilding. I
only need to modify archive gcc-e11b.zip to have support of djdev201.

Tests I did:
	- tests included with C+ libraries
	- building egcs-1.1a itself
	- building patched version of RHIDE-1.4.5 (patches are needed
          as egcs-1.1 gives more warnings as earlier compilers)
        - building my own software (mainly C++)

I began to try to build DJLSR202 with egcs-1.1 but met some problems
as egcs does more strict control of source code and gives warnings
where earlier compiler failed to do this (options -fqual-cast etc.)
I didn't finish building DJLSR202 but when I'll suceed I'll perhaps
send patches I needed.

That is one of reasons I asked this. When DJGPP port of gcc-2.8.1 were
put in v2gnu/alphas I didn't get any response about possible problems
before it was released (but there were problems)

One more thing. In previous message I also mentioned PGCC. I tried to
build it and was not satisfied with results:
   - libstdcxx.a build with pgcc-1.1a with options -mpentium -O6
     failed many tests (not from testsuite as we don't have port
     of dejagnu) in directories libio/tests and libstdc++/tests.

As the result I returned to egcs-1.1a.
