I have attached a script and fortran source which shows this.
Maybe you could tell me if I'm trying something which is not
supported. I have run it with egcs-1.1.2 and egcs-19990502 on
Irix6.5, hpux10.20, and NT4SP3/cygwin. The fortran runs silently
(successfully) using the vendor's compilers on the Unix
systems, as well as with g77 on cygwin (yes, over 90 open files).
The failing appending writes don't return any error codes but the
stuff never shows up in the data file. I imagine this is too much
stuff to send to egcs-bugs, nor would it be relevant without lower
level diagnostics.
The first version of append.f wasn't exactly what I meant, but
close enough. Well, in the second version I left out an endfile,
but putting it in doesn't make any difference, but now it's in.

Definitely submit the best bug report you can on this problem, in
case we can fix it before the release!
Thanks for the good news in the rest of your email!
