I am trying to get a recent version of gcc 4.8.2 up on my machine.
For a minimal source file, I get errors depending on the order of the
-arch flags. (I have used +universal, although in fact some of these
same errors occur even without that, strangely)
Specifically, `-arch x86_64 -arch
I am surprised that it even worked at all in the first case; last I heard,
FSF GCC did not support multiple `-arch` flags at all...
See gcc docs here: http://gcc.gnu.org/onlinedocs/gcc/Darwin-Options.html
The code that the Apple version of gcc uses to support multiple arch flags
can be found
