The workaround you mention only applies to building the mingw specific
bits in Cygwin/Winsup, and not applicable to general class of C++ code.

FYI, libstdc++-v3, as part of gcc-2.97, uses exceptions internally, and 
the current code will pull in various bits of eh.o(libgcc.a), even when 
building winsup/cinstall with exceptions rtti etc turned off. I may have 
a workaround/solution, but haven't tested it yet.

And there is nothing we should do about it other than inform users that it
is to be expected and exactly what the remedy is.
