There is one difference to the former script, though.  Because no
directory is specified, the revision number you get is the highest one
of the whole repository.  This means that it is increased also if you
don't change anything in the source tree but update trunk/manual.

If you prefer the highest revision number of any file in trunk/source
only, you could do something like:

svnversion -c ./source |
   sed -ne 's/^[0-9]*:*\([0-9]*\).*/#define luatex_svn_revision \1/p'

I currently get

#define luatex_svn_revision 3441

and I would get the same revision number even if something in the
manual tree was updated meanwhile.

A disadvantage is that svnversion's argument contains a relative path
which doesn't allow you to run build.sh from any other directory but
trunk.  But the file build.sh itself contains relative paths too,
therefore it won't work anyway.

An easy way to allow people to call, for instance,
./svn/trunk/build.sh or ../../../build.sh is this:

--- build.sh	2010-02-21 16:34:00.000000000 +0100
+++ build.sh-new	2010-02-21 20:47:24.000000000 +0100

  export CONFIG_SHELL

+cd `dirname $0`

 # try to find gnu make; we may need it
 MAKE=make;
 if make -v 2>&1| grep "GNU Make" >/dev/null


It's quite likely that it works on MSYS too, but it can't hurt to
test it there.


Martin, your assumption is almost right, I've 

LANG=en_US.UTF-8
LC_COLLATE=C

for the same reason as Taco.  Another reason is that it's not very
useful to get error messages in German because I often have to post
them to international mailing lists.  I'm grateful that Khaled Hosny
doesn't post them in Arabic. :)

Regards,
