unifdefall: print debugging output to stderr
unifdefall: correct exit status if the clean-up rm fails Reported-by: Bob Proulx <bob@proulx.com>
Remove sccs, cvs, and svn revision tags.
Improved debugging support. Add line numbers to unifdef's debugging output. Flush the output stream on each line when debugging to ensure stdout and stderr are properly interleaved. Add a debugging mode to unifdefall.sh which outputs its intermediate working files.
unifdefall: tidy copyright notice to match unifdef.c
Add Jonathan Nieder to unifdefall's copyright declaration.
unifdefall: look for unifdef in $(dirname $0) For debugging and for the test suite it is convenient is unifdefall can be run in place without relying on unifdef being installed elsewhere. So change unifdefall to look for unifdef in the containing directory. For compatibility, if unifdef is not present in the directory containing unifdefall, fall back to searching the $PATH for it. Some one might have installed unifdef and unifdefall to different directories. With this change, 'make test' no longer fails in if1-a.sh when unifdef is not present on the $PATH. Also, the test suite will be a little better at catching new regressions if an old version of unifdef is installed, since the unifdefall tests will no longer be testing the installed unifdef.

unifdefall: optimise the loop that builds the unifdef command. The old code used a shell loop to convert each controlling macro definition into a command-line argument, reading the macro definitions file each time. The new code converts the list of controlling macros into a sed script which can run through the list of macro definitions in one go. Add some explanatory comments, since the code is quite meta.

unifdefall: remove debugging remnants.
unifdefall: update copyright dates.
unifdefall: portability: do not try to use EREs with sed BSD sed uses -E and GNU sed uses -r to specify that extended regular expressions should be used instead of BREs. Some of the sed scripts have been simplified by relying on 'cpp -dM' to produce lines of the form '#define MACRO value', with a single space as delimiting whitespace. While we're modifying the sed scripts, also change the shell quoting script to correctly capture more characters when they appear in the right-hand sides of macro definitions (e.g., $).

unifdefall: allow spaces in $TMPDIR Submitted-by: Jonathan Nieder <jrnieder@gmail.com>
unifdefall: portability: avoid mktemp -t GNU mktemp interprets the argument after -t as the entire template and errors out if it contains no XXXX substring. BSD systems, on the other hand, treat the argument as a prefix for the mktemp template and use it verbatim, resulting in long, ugly filenames like foo.XXXXX.e30GuhHVzU if the string contains embedded Xs. So avoid -t and use TMPDIR explicitly. Submitted-by: Jonathan Nieder <jrnieder@gmail.com>
Use $() instead of `` in unifdefall.
FreeBSD cvs id isn't relevant in this file in the upstream version.
