[PATCH] Make compilation of preloaded module glue -Wstrict-prototypes clean

[Lennart Poettering]

When generating the preloaded module glue code libtool generates invalid
prototypes without argument lists. When compiling with slightly fascist
compiler options (-Wstrict-prototypes) this has the effect of causing
gcc to print gazillions of warnings when the final libtool call is done
-- for each symbol one.

This fix uses GCC's diagnostic pragma to override the
-Wstrict-prototypes setting for the generated code and thus makes GCC
shut up.

I proposed a patch that replaced the invalid prototypes by valid ones
earlier this year, which didn't get accepted. So here's a patch that
leaves all the current code in place but makes sure GCC doesn't complain
anymore about it.
