arm.obj : warning LNK4221: This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library
}

File in question:
http://mxr.mozilla.org/mozilla-central/source/xpcom/glue/arm.cpp

Included here:
http://mxr.mozilla.org/mozilla-central/source/xpcom/glue/objs.mk#72

Only actually does anything #if defined(MOZILLA_ARM_HAVE_CPUID_DETECTION), which is set here:
http://mxr.mozilla.org/mozilla-central/source/xpcom/glue/arm.h#110
http://mxr.mozilla.org/mozilla-central/source/xpcom/glue/arm.h#115

ie:
if defined(__linux__) || defined(ANDROID) || (defined(_MSC_VER) && defined(_M_ARM))
Flags: in-testsuite-
Attached patch Patch v1 (obsolete) — — Splinter Review 
Adds a |ifeq (arm, $(TARGET_CPU))| around the arm.cpp line.

Builds fine locally with MSVC 2010 and the LNK4221 warning in comment 0 no longer appears.
