[ssa branch]Fwd: [Introspector-developers] Build instructions for the cywin ssa branch

[James Michael DuPont <mdupont777 at yahoo dot com>]

Dear Joe,
Would you be so kind as to run the ssa-branch against
the linked file here,
under cygwin, they are segfaulting.

http://introspector.sourceforge.net/cygwin/del_op.ii

The two bugs that seem to be with the
-fdumptranslationunit command. 
Segfaults in the compiler.
floatformat will go away if you say -save-temps, strangely enough.
very odd that other one, is occuring in the first builds of
floatformat.c
/gcc/i686-pc-cygwin/libiberty/floatformat.c
