When compiling my project with emcc 1.40 we get the following errors that did not appear with 1.39.5;

> emcc --version
emcc (Emscripten gcc/clang-like replacement) 1.40.0 (634dfe9c7837119d3970c4145984b8f517e3e1ca)

Error: Aborting compilation due to previous errors

Was something changed in the GL ES emulation?

Why would it have worked before without adding these things to EXPORTED_FUNCTIONS?

I think this is


Sorry about this regression - please use the previous release until we tag a new one with a fix.

Sorry about that.  I broke this, and it also showed up a gap in our testing.


cheers,
