Actual problems why C++ exceptions doesn't work reliably with DJGPP port
of egcs is found (Lazlo Molnar and I). There is no need to use 
-fsjlj-exceptions. Seems that after corresponding fixes there is no
more significant exceptions related regressions against gcc-2.8.1 at all 
or egcs-1.1.1 under Linux.

About Win32 ports: I may be wrong but anyway I think it's worth to try -
	download some recent binutils snapshot and build it with
	configure option --enable-bfd-assembler and see if it works.
	At least I can say it helps for DJGPP port of egcs-1.1.1
	(I and Lazlo have tested that with AS.EXE I have built from 
	990120 binutils snapshot)
