Thanks, but:             
- The double "" after PERL_PATH makes the string un-terminated.

- Using "$$PERL_PATH" expands from make into "$PERL_PATH" on the command line

- If the Makefile looks like this:
PERL_PATH = "/Users/tb/projects/git/tb/pe rl"
$(PERL_PATH) check-non-portable-shell.pl $(T)
The command line will look like this:
"/Users/tb/projects/git/tb/pe rl" check-non-portable-shell.pl t0000-basic.sh ...

So I think that PERL_PATH should be quoted when it is defined in the Makefile.

Peff, many thanks. Please see V2 patch comming soon
