Causes ftnchek to
report whether any subprograms invoked by the program are never defined.
Ordinarily, if ftnchek is being run on a complete program, each subprogram
other than the intrinsic functions should be defined somewhere. Turn off
this switch if you just want to check a subset of files which form part
of a larger complete program. Subprogram arguments will still be checked
for correctness. Default = yes.
The -extern flag is now superseded by
the -usage=ext-undefined option. For the sake of convenience, the -extern
flag is retained, so that -noextern is equivalent to -usage=no-ext-undefined
option. The -extern switch may be retired eventually.
