The const fixes I proposed are easily isolated: they affect only the
src/regex.c file.
You are free to submit it or to forget about it.
In this file, const is used in a few places only, resulting in dozens of
warnings. Either
remove the use of const or use it everywhere it is needed.
There is always the option to #define const to nothing, but I won't favor
it.
