Problem with sketches using randomSeed() and random() about chipkit32-max HOT 4 CLOSED

WMath.cpp was missing from cores/pic32

Copied WMath.cpp from cores/arduino. Fixed srandom invocation to srand (stdlib) and random invocation to rand().

This is how working WMath.cpp looks like:

/* -- mode: jde; c-basic-offset: 2; indent-tabs-mode: nil -- */

Did you commit that to the master branch? It's not there, and I can certainly add it.

I am not changing the code from github, just my own local copy, so you can add it.

from chipkit32-max.

Done, and works.
