Since my Cygwin64 is a fesh installation, I wonder if I missed to
installe some needed packages... or is that error to be expected on

I found the problem (or at least I found *a* problem): There's a configure test "checking whether a fault handler according to POSIX works", which passes on 32-bit Cygwin but fails on 64-bit Cygwin. I'm attaching a file containing the configure test. Here's what happens in the 64-bit case:

$ gcc -o fault fault.c
$ ./fault.exe
$ echo $?

In the 32-bit case, the exit code is 0.

I don't know if this indicates a Cygwin bug or something wrong with the test.
