 This problem appears to be solved with the latest version
 of cygwin (as of jul 1 d/l)
 
 I still need help determining gcc3's MT-exception capability.
 Can anybody help me with this?
 
 Thanks a lot.
 
 Someone can close this bug (7168)

 I don't have access to a windows setup, so I am unable to help you. I
 suggest you email some of the people building current gcc under cygwin,
 the people who submit results to gcc-testresults, and ask them politely
 to try your sample code. 
 
 I suspect it works, but do not know for certain. The C++ results, in
 general, look quite good for cygwin with recent toolchains.

 Thanks, already done w/cc on the previous e-mail.
 
 Thanks for the help you are giving me anyway.
 
 btw: the example that's submitted with the bug will not work with gcc 3,
 so this presents another problem of how to specifically test for this 
 error
 in the gcc 3.0 tree.

 Can somebody verify that C++ MT-exceptions work in the latest
 gcc 3.0 builds for cygwin?  If true, I can volunteer to build the 
 binaries.

 I reported this to the cygwin lists as well,
 I am not sure this is a libstdc++ issue, but it might be an issue in 
 libgcc,
 and since there isn't a cygwin gcc 3.0, maybe there's an expert in this
 that's listening on this list as well.
 
 Thanks a lot.

 We no longer support 2.x in the gerneral libstdc++ development; the code
 has been completely rewritten.  If you are having a cygwin problem, you
 should report it to the cygwin lists.
