Hi guys,
I currently set:
.POSIX=
In a Makefile thinking that it would enable only POSIX
functionality, and was fidgeting around with the Makefile trying to
get it to work. In short, I used secondary expansion, it worked, then
compared the output from gmake and it failed (because they have the
.SECONDEXPANSION keyword). POSIX doesn't mention secondary expansion,
so obviously it's not a POSIX feature.
So I was wondering if secondary expansion is enabled by default
with .POSIX instead of being disabled like it should on pmake?
Thanks,
-Garrett
