PAC_PROG_F77_LIBRARY_DIR_FLAG

Determine the flag used to indicate the directories to find libraries in

Notes

Many compilers accept -Ldir just like most C compilers. Unfortunately, some (such as some HPUX Fortran compilers) do not, and require instead either -Wl,-L,dir or something else. This command attempts to determine what is accepted. The flag is placed into F77_LIBDIR_LEADER.
