FWIW, rebuilding m4 1.4.13 picks up the new libsigsegv0 dll, but it still
exhibits the crash when used under cygwin-1.7.0-51 (ie. the bug is not whether
libsigsegv was linked in static or dynamic, but that libsigsegv is over-eager
to claim that all SEH faults should be handled like SEGV faults). The
particular m4 crash is gone with cygwin1.dll built today (thanks to my recent
newlib fflush patch). Meanwhile, I will be packaging m4-1.4.13-2 to pick up
the new libsigsegv0 (so that when Bruno does fix libsigsegv, I don't have to
rebuild m4-1.4.13-3 to relink against the fix), and that will also include a
one-liner patch (currently in m4.git) that makes the particular m4 crash go
away even if you don't have a self-built cygwin1.dll.
