Re: Slightly different interpretation of $PATH between Bash and Perl

[Peter Buckley <peter dot buckley at cportcorp dot com>]

IIRC system() in perl does the same thing as make invoking a shell. It 
uses ash (sh) instead of bash. It sounds like things are different
because 
of the two different shells being used. 

I don't remember if it is recommended, but I have heard people say that 
you can make a copy of bash.exe and rename it to sh.exe and delete or 
rename the old sh.exe so perl and make will use bash instead of ash. 

HTH,
