Error while installing gnustep-base 1.15.3

[Chris B. Vetter]

Hello,

while trying to install 1.15.3, make exits in Tools/ with

  Making install for tool make_strings...
    Installing tool make_strings...
  gmake[1]: Leaving directory
`/Users/cbv/Public/gnustep-base-1.15.3/Tools/make_strings'
  /bin/sh: test: argument expected
  gmake: *** [after-install] Error 1

Apparently the problem is with

        if [ ! -f $(GNUSTEP_DOCUMENTATION_MAN) ]; then \

which doesn't exist (anymore).
Changing it to GNUSTEP_DOC_MAN seems to fix the problem, though I'm
not sure it's pointing to the correct directory.

Cheers,
