unrecognized command line option `-Wno-c++11-extensions` on mac

[brson]

Building rust-azure I see error: unrecognized command line option "-Wno-c++11-extensions". My compiler is

i686-apple-darwin10-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) ( LLVM build 2336.1.00).

Running on OS X 10.6.8.

mozjs also has such a switch, but it is autodetected by configure. We'll need to configurize (lightly!) rust-azure to do similar detection to fix this.

[brson]

I'll do that tomorrow.

After making changes to the makefiles to get past this error, the azure build fails with mfbt (and Gecko) require at least gcc 4.4 to build, and I have 4.2.

I have gcc 4.2.1, so I'm not sure how you hit this. Where does that error come from? Did you grab configure from upstream or something?

[brson]

The error comes from Compiler.h

Since this code is liberated from Gecko, I think we can remove this check.

I'm not sure what part of mfbt requires gcc 4.4, or even what mfbt is. We do have a few files in the mfbt directory though.

IIRC, mfbt is shared code, similar to NSPR but much newer and with less ambition.
