Readline 4 is a bit old, but it's what's on the RHEL box where I'm 
building the rpm.

OK, you're not using an installed copy of gtksourceview, so gretl 
is building this library from the code that's bundled under gui2.
Apparently the configure check for gnu_regex passed since 
-DNATIVE_GNU_REGEX is being passed among the CFLAGS. And 
apparently regex.h is found, since there's no complaint from the 
compiler about that being missing.

Beyond that, I'm puzzled: regex.h is found, but it doesn't seem to 
have anything useful in it!  It's not defining struct re_registers 
or RE_SYNTAX_POSIX_MINIMAL_EXTENDED.  

You could work around this by installing gtksourceview.  But 
looking in this area, I see that the build process for the bundled 
gtksourceview was broken for the case where native GNU regex is 
_not_ available: this is now fixed in CVS.  Although this doesn't 
seem to be your case, it might be worth trying to build gretl from 
CVS and see if that goes OK.
