Buglets in older version (1.6.4)

[Bruce Korb]

1.  It needs a configury test for "diff".  The build _depends_ upon a
    GNU-diff program.  Better fix:  remove dependency

2.  Build problems on HP/UX:

$ ../config.guess
../config.guess[645]: 17639 Abort(coredump)
hppa2.0w-hp-hpux11.11
$ gmake DIFF=gdiff

*** shared version of the library, which you do not appear to have.

*** Warning: linker path does not have real file for library -lcrypt.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libcrypt and none of the candidates passed a file format test
*** using a file magic. Last file checked: /usr/lib/libcrypt.a
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.

*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.
