#ifdef REGEXP_PREFIX
/*
* An application can specify REGEXP_PREFIX to use the prefix to
* regexp routines (regcomp, regexec, regerror and regfree).
*
* Note that the regexp routines are the ones in the standard C
* library. It is no problem to override those routines by an
* application (with appropriate care of link order).
*
* However, use of REGEXP_PREFIX is required when you use
* AddressSanitizer (ASan). It doesn't work well, because it tries to
* replace regexp routines in the standard C library but actually
* replaces this implementation. Since it doesn't know about this
* implementation, it's not compatible.
*
* For example, in the Makefiles of GnuPG, we do specify REGEXP_PREFIX
* with "gnupg_".
