Hi,

How do I build a 64 bit binary on Mac OS X with the Make build system?
It looks like gyp forces `-arch 386` into all Makefiles, regardless of
what `target_arch` I set in the gyp file.

I am also curious about this. Thanks!

So the (temporary) solution seems to be do uncomment cflags.append('-
arch i386') and ldflags.append('-arch i386') in the generator/make.py
file.

In the Linux world gyp punts the 32-bit/64-bit issue off to the gyp files.

If Xcode/MSVS have some native conception of the target arch, it
probably falls on gyp to make a cross-platform hook for specifying
this kind of thing.
