Thanks! One other question; why the '?' mark? I
was
Googling for information on gcc, and it listed
'cxx='
sans a question mark in it.
It means "set CC to this value if it's not already
set to something".
Some ports already know they need a newer version of
gcc (using
"USE_GCC="), and the "make world" infrastructure to
rebuild the
kernel/userland need to use the system-provided
compiler, so using
the question mark lets things which know better use
the exact
compiler they want.
Thanks! I could not find that information anywhere,
although I am sure it does exist.
Does the make.conf manpage need to be updated? It doesn't appear to reference
either USE_GCC= or CC= or CXX= at all..
