Hello,

I wonder why the result worked under wine then, though; strange.
Must be the very old wine version on the machine I initially used for
testing (where the program indeed works). With newer wine I can
reproduce the non-working.
So, with the hint of grischka I came up with the attached patch which
implements the plumbing in the startup files so that Christians example
signal.c works. It's not in any way a real implementation of SEH, but
that isn't necessary.
I'll wait for feedback on this and not yet commit to git.
Ciao,
Michael.
