Hi Werner, In the "Portable Shell" node of "info autoconf", I see
... include a space after the exclamation point in interpreter
specifications, like this:
#! /usr/bin/perl
If you omit the space before the path, then 4.2BSD based systems (such as
DYNIX) will ignore the line, because they interpret `#! /' as a 4-byte
magic number. ...
Most of the scripts included in the groff distribution ignore this
recommendation, so here's a patch to make them conform:
Miscellaneous script portability enhancements.
* aclocal.m4: (GROFF_CSH_HACK): add space in shebang prototype for
generated conftest.sh script, conforming to portability recommendation
in autoconf docs.
* configure: likewise, for code generated by GROFF_CSH_HACK
* install-sh: add space in shebang, conforming to portability
recommendation in autoconf docs.
* contrib/eqn2graph/eqn2graph.sh: likewise
* contrib/gdiffmk/gdiffmk.sh: likewise
* contrib/gdiffmk/tests/runtests.in: likewise
* contrib/grap2graph/grap2graph.sh: likewise
* contrib/groffer/groffer.sh: likewise
* contrib/mm/mmroff.pl: likewise
* contrib/mom/momdoc/appendices.html: likewise
* contrib/pic2graph/pic2graph.sh: likewise
* font/devps/generate/afmname: likewise
* src/devices/xditview/ad2c: likewise
* src/preproc/eqn/neqn.sh: likewise
* src/roff/grog/grog.pl: likewise
* src/roff/grog/grog.sh: likewise
* src/roff/nroff/nroff.sh: likewise
* PROBLEMS: likewise, in embedded script examples.
You will note that I have kept the adjustment to configure, which would
result from the aclocal.m4 change, in the patch, (and in the above ChangeLog
entry), although you may prefer to regenerate it, (and amend the ChangeLog
entry accordingly), in any case.
Best regards,
Keith.
