I haven't been able to get guile to compile under Cygwin (just a
compilation error I haven't had time to track down), but I was able to
quickly try the above. I get:

Testing: test-native-call_10
call_10.c:9: assertion failed: e == 4
/bin/sh: line 1:  7063 Aborted                 (core dumped) ./$test
make: *** [Makefile:31: test-native] Error 134

Despite what it says about a core dump, I find no such thing. Just a
file with the same name as the executable suffixed with ".stackdump".
(I did attempt to configure the Cygwin dumper before running the
tests.) Unless somebody suggests otherwise, I think the error message
is more useful.
