With gcc-3.4.4 I get:

$ gcc -O3 -c gccO3bug.c
gccO3bug.c: In function `main':
gccO3bug.c:13: warning: function called through a non-compatible type
gccO3bug.c:13: note: if this code is reached, the program will abort

S.th. wrong with your testcase?

Can you try if the Perl extension compiles with gcc 3.4.4, and please
send me a patch for the testsuite:

Running make test
make[1]: Entering directory 
`/home/gerrit/.cpan/build/C-DynaLib-0.55/DynaLib'
make[1]: Leaving directory `/home/gerrit/.cpan/build/C-DynaLib-0.55/DynaLib'
/usr/bin/perl.exe "-Iblib/lib" "-Iblib/arch" test.pl
1..10
ok 1
not ok 2
Can't load -lc: dlopen, Win32 error 5 at blib/lib/C/DynaLib.pm line 52.

Giving up.
make: *** [test_dynamic] Error 13
   /usr/bin/make test -- NOT OK
Running make install
   make test had returned bad status, won't install without force
