I hit a compile failure when compiling js 32-bit ARM-simulator shell on m-c rev d7e156a7a0a6.

autoBisect shows this is probably related to the following changeset:

Lars, is bug 1125837 a likely regressor? This blocks fuzzing 32-bit ARM simulator builds on Mac.

Credits to Jan for suggesting how to fix this.

rs=jandem over IRC, and I've checked that this does fix the broken Mac 32-bit ARM-simulator build.

Funny, I compiled with Clang locally, but it didn't catch that problem.  I guess Clang on Linux is not like Clang on Mac.
