Commit Message

Giuliano Procida May 4, 2020, 12:34 p.m. UTC
This patch eliminates all calls to regcomp except that by
regex::compile itself.

	* src/abg-corpus-priv.h: Mechanically substitute use of
	regcomp with regex::compile wrapper.
	* src/abg-suppression-priv.h: Ditto.

There are no behavioural changes.
