There is historically two regex interfaces: regexp & regex.
_Both_ have regerror(), it is right.
Only _one_ interface can be picked. If you pick regex module,
you pick regerror() too from same file. Be shure that
your regerror() call not first call in pgm in this case.
If you pick regexp module,
regerror() from there must be first in library.
Current tsort does just right thing placing it first.
I just build libcompat without any problems.
Maybe better variant will be to merge both regerror() function
into one function which is ruled by setting global variables
into regex & regexp.
