Hi, When the included regex is used I must prepend -I$(srcdir)/gllib to CPPFLAGS to ensure that the gnulib regex.h is included in the sources. (when this is not the case, I _must_ not do that!) This raises 2 questions:
1. how do I know elsewhere in the configuration process that the included regex is used? the authoritative variable is ac_use_included_regex, but it is not cached, so sub-configures cannot access it. 2. what if there is some other gnulib package xeger with the same modus operandi? (i.e., if xeger is used, I must prepend -I$(srcdir)/gllib to CPPFLAGS and if it is not, I must not). what if regex IS used but xeger is NOT? I propose that regex.h is replaced with regex.in.h just like fnmatch.in.h (which has no @@ either). This would solve the problem without any action from the users of gnulib.
