[Rlib-devel] GCC4 warning fixes part2

[Zoltan B. <zb...@du...>]

Hi,

part 2, this time I fixed the following warnings to decrease the flood:

warning: passing argument N of 'func' discards qualifiers from pointer
target type
warning: initialization discards qualifiers from pointer target type

and every fallout that would cause incompatible pointers in assignment
warnings.

Reasoning: many functions that accept a "gchar *" parameter don't write
back to the string so they can be marked "const gchar *".
Indeed, most calls to them are done with constant strings.

Best regards,
