./src/jsapi.cpp: warning C4117: macro name '_CRT_USE_BUILTIN_OFFSETOF' is reserved, '#define' ignored

I can see (when the build fails), presumably otherwise the warning is hidden. Maybe we should remove this while we are at it.

This comes from https://searchfox.org/firefox-main/rev/167d26cbe19af2e0ebe11fa6ad7a3755b59c3c64/build/moz.configure/bindgen.configure#351

Hmm, I wonder if this is a difference between clang-cl and the real cl? I'll try and check this evening what the build on my windows system used.
