dnl I haven't thought about it specifically, but since some of my macros have
dnl gone into other autotools, and I'd like some others to go there too, I think
dnl GPL makes the most sense.  Is GPL ok w/ you?
dnl 
dnl There's no risk making the macros GPL'ed even for people who don't like the
dnl GPL, b/c to use a package, one only needs the configure script that's
dnl generated out of these macros, not the .m4 code itself.
dnl 
dnl As for this check_lib2.m4 function, a few of us tried to convince the
dnl autoconf maintainers that our version makes more sense as the default
dnl behavior; but they still wanted to keep the older macro w/ the older
dnl behavior, which I think is just wrong.  Sooner or later the official
dnl check_lib will change or there'd a new macro offered; more and more people
dnl like the more logical behavior that my macro has.
dnl 
dnl Cheers,
dnl Erez.
