I should have emphasised that this is a batch file that runs from cmd.exe.
So foo.bat contains:

sh -s %1 < \a\b\c\foo.sh

Thanks for the hint.

: Well, since we don't have the contents of the script nor the `Weird

Ok. I'll try to put together a small sample tomorrow.

: Have you tried `sh /a/b/c/foo.sh %1'?

Yes. That works (as expected) --- but the semantics are subtley different.

I've got a script that I want to have execute irrespective of the drive
it happens to installed on. In this instance, I have a bunch of files that are
installed in directory x:\a\b\c. The drive relative path (in Win32 terms)
is \a\b\c.

I can get to the file in Cygwin only by giving an absolute path //x/a/b/c.
Thus although sh /a/b/c/foo.sh "works" from a cmd.exe batch file --- it
cannot find the file in a drive relative way --- only \a\b\c\foo.sh can
do that.

Let me know if there's any confusion here.

So, the only way that I could think of to get hold of the shell script in
a drive relative way was to get a Win32 batch file to locate the script:

foo.bat:
	sh -s %1 < \a\b\c\foo.sh

foo.sh:
	# Rest of script

This way, I can "execute" the shell script from a Win32 command shell. Or
I could until I tried b19 :-(
