--- Comment #26 from Denis Excoffier <gcc@Denis-Excoffier.org> ---
After more investigation, it seems that the culprit can be
--disable-sjlj-exceptions. Since the beginning (last Sunday), each time i use
it on the command line, the build fails and each time i don't use it, the build
succeeds.

Please would you mind trying again a cygwin build, but with
--disable-sjlj-exceptions this time. Especially for those where the build
succeeded. For Mikael (see comment #2), it is more than probable that he used
--disable-sjlj-exceptions instead of my gmp kludges known by nobody except by
me.
