New rc snapshot available (1998-10-28)

[Tim Goodwin <tgoodwin@cygnus.co.uk>]

A new snapshot of rc is available from here.

     ftp://ftp.cygnus.com/pub/tgoodwin/rc/snap/rc-1.5s19981028.tar.gz

Nothing too major has changed, although rc has just acquired its first
idiom from C 9x!  (With suitable autoconfiscation for older systems.)
Relevant ChangeLog entries are appended.

Thanks to Bengt Kleberg and Jeremy Fitzhardinge for reporting problems
with the previous snapshot.

Tim.

  Tidiness: makenonblock() was a rather poor choice of name for
  a function which makes a file descriptor *not* nonblocking :-).

  Portability: apparently some systems declare `char *basename(const
  char *)' in system header files.  Changing our basename() (in
  history.c) to match this prototype allows it to be compiled on such
  systems, and is harmless.  (Harmless, that is, if no system declares
  `char *basename(char *)'.)

  Bug: system-bsd.c needs to include "wait.h".

  Warnings: some versions of gcc warn about "ambiguous" `else' clauses.

  Portability: assigning va_list objects doesn't work everywhere (Linux
  on the PowerPC, specifically).  Use the C 9x invention va_copy()
  instead, if it exists, otherwise fall back to assignment.

  Documentation: help HP-UX users by mentioning that you need `cc -Ae'.
  Also, HP-UX make will build rc in a separate directory.

  Tidiness: remove unused functions from print.c.  Anybody wanting to
  use this library in another project should follow the pointer in the
  documentation to an improved version.
