Re: how to (correctly) modify GNU Make so that separate shell is always spawned for each command

    either defined in the environment initially or set on the command line,
    and ***if its name consists only of letters, numbers, and underscores.***
    Some shells cannot cope with environment variable names consisting of
    characters other than letters, numbers, and underscores.

Yes thank you I missed this paragraph.  My bad.  I read the one above but did 
not see this one.


>Well, the *real* simplest is to make the variable names conform to the
environment syntax, but that isn't always an option.


Yes I wish I could.  Intel's dpdk software makefiles are exporting variables 
with dashes....  Auwe!!  I am not an Intel employee.  
Turns out, variables with dashes, are accepted from GNU Make by some some 
shells, not others.  
Case in point, in works on dash 0.5.5.1.  But it turns out, what I was hacking, 
was the latest dash, 0.5.8.  It does NOT work on that one...  I thought, I will 
just grab the latest and go with it.  Bad mistake :)  

Thank you everybody.
