I take your point so we should eliminate the extra GNUWin32 tools dependency
since that appears to be easy to do.
Here are the issues and my suggested solutions.
(1) cat.
I think the best thing to do with cat is to replace it by a series of echo
commands. See scripts/make_tarball.sh script where the usage message is
printed out that way. "echo" is supplied by the bash shell so using it
should be okay for win-bash (but please check).
(2) sed
We use that command in plplot-test.sh to allow cross-platform parsing for
all the different unix shells. We should keep that use of sed as an
alternative for just that reason, but if (say) HAVE_BASH is set (we will
have to provide a bash test for our CBS to set that up), the script should
use the powerful bash parsing features instead of sed.
A google search came up with one bash parsing feature which appears to be
exactly what we need. I illustrate this parsing feature as follows:
[EMAIL PROTECTED]> xxxx='hello=3941'
[EMAIL PROTECTED]> echo ${xxxx#*=}
3941
So this method of parsing out everything after the equals sign in a
plplot-test.sh option should just work with win-bash, but please check.
(There is also one other use of sed in plplot-test.sh, but it is just a
backup if some other method fails so we probably do not need to deal with
it.)
Anyhow, it is past time for me to get some sleep, but if one of you guys
does not implement the above simple changes first, I will do that tomorrow
evening (European time) and that may be all we need to get ctest scripts to
work on bare windows (without the extra GNUWin32 tools dependency).
