Revision 1.26, Fri Jul 15 19:33:01 2016 UTC (4 years, 11 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_14_1, VERSION_1_13
Changes since 1.25: +1 -3 lines

To remove the const qualifier from a pointer to an object - either
because we know it is actually mutable or because we are passing
it to a function that doesn't accept a const object but won't
actually attempt to modify it - simply casting from (const type *)
to (type *) is legal C and clearly expresses the intent.
So get rid of the obfuscating UNCONST macro.
Basic idea discussed with guenther@.
