I just tried building 21.2.35 with 'make -j4', i.e. 4 parallel jobs.
It seems to have worked ok (I got a working binary), but during the
build I saw the following:
gcc -c -g -Wall -Wno-switch -Demacs -I. -DHAVE_CONFIG_H -I/usr/X11R6/include
-DDEFINE_TOP_LEVEL_EMACS_SHELL /data/scratch/ge204/src/XEmacs/xemacs/src/EmacsShell-sub.c
mv EmacsShell-sub.o TopLevelEmacsShell.o
mv EmacsShell-sub.o TopLevelEmacsShell.o
mv: `EmacsShell-sub.o' and `TopLevelEmacsShell.o' are the same file
make[1]: *** [TopLevelEmacsShell.o] Error 1
gcc -c -g -Wall -Wno-switch -Demacs -I. -DHAVE_CONFIG_H -I/usr/X11R6/include
-DDEFINE_TRANSIENT_EMACS_SHELL /data/scratch/ge204/src/XEmacs/xemacs/src/EmacsShell-sub.c
make[1]: Leaving directory

/data/scratch/ge204/src/XEmacs/xemacs/src/EmacsManager.c
I don't quite understand this, but maybe sombody could tweak the
makefiles some to avoid this?

Where are you putting the -j4? I have a small cluster I build with
and I add the -j4 flag to the Makefile/GNUmakefile.
For 21.1.x I add the following line just before the RECURSIVE_MAKE=
rule:
MFLAGS += -j4
For 21.2.x I just add the flag to the RECURSIVE_MAKE= rule:
RECURSIVE_MAKE=$(MAKE) -j4
This gets me the best utilization of all the proccessors. There is
more information on the cluster on my web site
http://netwinder.org/~seanm.

try replacing mv with cp and/or adding EmacsShell-sub.{o,rtl} to both dependency
lists.

In order to save my hands, I am cutting back on my mail. I also write
as succinctly as possible -- please don't be offended. If you send me
mail, you _will_ get a response, but please be patient, especially for
XEmacs-related mail. If you need an immediate response and it is not
apparent in your message, please say so. Thanks for your understanding.
