| This patch is not complete: lib-link.m4 has 3 entry points
| AC_LIB_LINKFLAGS, AC_LIB_HAVE_LINKFLAGS, AC_LIB_LINKFLAGS_BODY, and
| your patch splits only one of the three.
|
| Actually I don't want to split these three macros, because the user

| have to write a single macro call, not two. Also, I don't want to add
| an extra 'package' argument to the macros, because it would complicate
| the calling conventions of the macros for a rare usecase.
|
| Instead, I'm adding a separate macro AC_LIB_FROMPACKAGE, with which
| you can declare which library comes from which package. Like this:
|
|    AC_LIB_FROMPACKAGE(avcall, ffcall)
|    AC_LIB_FROMPACKAGE(vacall, ffcall)
|    AC_LIB_LINKFLAGS(avcall)
|    AC_LIB_LINKFLAGS(vacall)

does this create two new options
- --with-libavcall-prefix and
- --with-libvacall-prefix
instead of one option
- --with-libffcall-prefix
as in my patch?
