[PATCH] testsuite: Add -fshort-enums to pr33738.C

[Torbjörn SVENSSON]

Ok for trunk and releases/gcc-14?

--

For some targets, like Cortex-M on arm-none-eabi, the -fshort-enums is
enabled by default. For these targets, the test case fails as
sizeof(Alpha) < sizeof(int).
To make the test case bahave identical for targets that does enable
-fshort-enums and those that does not, force the option in the test
case and verify that the warning is emitted.

Regtested on x86_64-pc-linux-gnu and arm-none-eabi.

gcc/testsuite/ChangeLog:

        * g++.dg/warn/pr33738.C: Added -fshort-enums and removed xfail.
