There is indeed a problem with AC_F77_LIBRARY_LDFLAGS here, and your
suggestion seems rather logical.
But there is no reason for AC_F77_WRAPPERS to require
AC_F77_LIBRARY_LDFLAGS; in _AC_F77_NAME_MANGLING one may simply (well, i
have no idea whether this is simple or not) link against Fortran
compiler to suppress this dependency and have a safer AC_F77_WRAPPERS
macro. Or did i miss something obvious?
