[Jeff Dwork]

There are two changes required to compile 19.34 on RH 6.2.

One relates to glibc-2.1.  Change src/systty.h as follows:

diff -c emacs-19.34/src/systty.h.orig emacs-19.34/src/systty.h
*** emacs-19.34/src/systty.h.orig Tue Jul  2 09:12:22 1996
--- emacs-19.34/src/systty.h      Fri Sep 29 17:36:27 2000
***************
*** 296,302 ****
--- 296,310 ----
  
  #ifdef __GNU_LIBRARY__
  /* GNU libc by default defines getpgrp with no args on all systems.  */
+ #if __GLIBC__  >= 2
+ /* glibc-2.1 adds the BSD compatibility getpgrp function
+    if you use _BSD_SOURCE, which Emacs does on GNU/Linux systems.  */
+ #if __GLIBC_MINOR__ < 1 || ! defined (__FAVOR_BSD)
  #define GETPGRP_NO_ARG
+ #endif
+ #else /* __GLIBC__ < 2 */
+ #define GETPGRP_NO_ARG
+ #endif /* __GLIBC__ < 2 */
  #else /* not __GNU_LIBRARY__ */
  #if defined (USG) && !defined (GETPGRP_NEEDS_ARG)
  #  if !defined (GETPGRP_NO_ARG)

The other is in src/s/gnu-linux.h, where setpgrp is defined in a way
that conflicts with a definition in unistd.h.  Change
src/s/gnu-linux.h as follows:

diff -c emacs-19.34/src/s/gnu-linux.h.orig emacs-19.34/src/s/gnu-linux.h
*** emacs-19.34/src/s/gnu-linux.h.orig  Mon Jul 15 19:17:05 1996
--- emacs-19.34/src/s/gnu-linux.h       Fri Sep 29 16:35:12 2000

  #define BSD_PGRPS
! #define setpgrp(pid,pgid) setpgid((pid),(pgid))
--- 292,296 ----
     actually set a process group. */
  
  #define BSD_PGRPS
!      /* this conflicts with the same definition in unistd.h - jrd 092900 */
!      /* #define setpgrp(pid,pgid) setpgid((pid),(pgid)) */

Works fine for me after these changes.
