Hey, calm down, I wasn't asking you to become solaris
gdb maintainer. :-)  To fix this, all it takes it do something like
adjusting the affected functions to use char buffers and memcpy, instead
of playing tricks with pointers.  A bit of care has to be taken due to
the ifdefery in place, but nothing major.  You're in a good position to
fix it, because, well, you have the compiler handy.  If not taking care of it,
is there somewhere where I can download binaries of a recent enough
gcc that triggers those warnings?  A bugzilla PR with the warning/error log
would also be nice.

It's build-dir/gdb/testsuite/gdb.log.  If you run a test with
something like:

make check RUNTESTFLAGS="--debug -v -v foo_test.exp"

you'll find much more debug info in a
build-dir/gdb/testsuite/dbg.log file.
