[RFA] testsuite/gdb.c++/cplusfuncs.cc: remove superfluous casts

[Michael Elizabeth Chastain <chastain@cygnus.com>]

Here is a small patch to remove some superfluous casts from
testsuite/gdb.c++/cplusfuncs.cc.

The casts are in a group of marker functions whose purpose is to help
figure out which demangler is in use (v2 or v3).  When I originally wrote
these marker functions, I made all the return types 'int' for uniformity.
This uniformity is actually not needed; the test script is not even
looking at this return type.  And it involves some pointer->integer
casts which cause problems on some platforms.

Testing: I tested this on native Red Hat Linux 7 and native Solaris 2.8,
with both gcc 2.95.3 and gcc 3pre 2001-05-25.  Kevin Buettner tested
on ia64-unknown-linux with gcc 2.96.

OK to apply?
