"Error 2" is not a GNU make error message. It's difficult to be 100%
sure without the actual message, but that typically means that the
subprocess make invoked (the shell in this case) exited with an error
code of 2, rather than 0.
I suggest you examine the output command line generated by make
vs. gmake and carefully compare them to determine where they're
different.

There's no way to know since you haven't provided enough information,
and I can't reproduce the problem.
ne> gmake -ver
ne> GNU Make version 3.79, by Richard Stallman and Roland McGrath.
You might try the latest version (3.79.1) and see if that helps at all.
You might also try the patch below; there is a problem that was recently
reported and fixed on certain rare, specific types of command lines.
