Building 1.12.0 with glib-2.43 has the following const warnings.

[Rudi Heitbaum]

Hi Werner,

Understood and agree.

I have proposed the 3 patches that address the warnings that should be fully backward compatible. I skipped fixing the the 'const' qualifier in tests/testdrv.c - given it is a test and - that the local char* arg_list is used for both const char and char pointers.

Hope these are acceptable.

Thanks
Rudi

Actually this is a useful thing but this and the new keywords break all
kind of existing code.  We can't change everything for the benefit of a
new compiler and with that break bulding the software on dozens of other
platforms.
