egcs+CYGWIN32 -- needs special linker help?

And it turns out that I do indeed need a newer release of binutils than
2.8.1. The UNIQUE_SECTION and ASM_OUTPUT_SECTION_NAME etc macros break 
with the last stable binutils release, but does work with the development 
snapshots. For those who're interested in a (semi-)working egcs + cygwin32, 
email me for a recipe.

It's nice to have member templates and reasonable exception handling in
C++ w/out as an alternative to Intel's (pretty damned good) C++ compiler 
on win32.
