substitute-in-file-name does not work properly on
Apollo Domain/OS GNU Emacs. The problem seems to occur when
an environment variable contains a pathname which begins
with //hostname, as shown in a log below:

(emacs-version)
"GNU Emacs 18.54.2 of Mon Jun 12 1989 on sdcapol2 (Domain/OS)"

(getenv "JJ")
"-idir //javelin/udr2/sasdjb/h -idir /usr/include"

(getenv "KK")
"-idir /udr2/sasdjb/h -idir /usr/include"

(setq compile-command "/com/cc foo.c -b ../obj/foo.bin $JJ")
"/com/cc foo.c -b ../obj/foo.bin $JJ"

(substitute-in-file-name compile-command)
"/javelin/udr2/sasdjb/h -idir /usr/include"

(setq compile-command "/com/cc foo.c -b ../obj/foo.bin $KK")
"/com/cc foo.c -b ../obj/foo.bin $KK"

(substitute-in-file-name compile-command)
"/com/cc foo.c -b ../obj/foo.bin -idir /udr2/sasdjb/h -idir /usr/include"

The substitution of $JJ causes a loss of the string up to the
//javelin in the environment variable! The second substitute,
with env var KK works properly.

I copied this from an emacs session run as:
% emacs -q

from a /bin/csh with SYSTYPE="bsd4.2", running Domain 9.7

Thanks,
