cutealien 2ae2a551a6 Merging r5975 through r6036 from trunk to ogl-es branch.
GLES drivers adapted, but only did make compile-tests.

*
* The actual configuration options for a particular installation are stored

* or copied from one of the "canned" jconfig files that we supply. But if
* you need to generate a jconfig.h file by hand, this file tells you how.

* DO NOT EDIT THIS FILE --- IT WON'T ACCOMPLISH ANYTHING.
