*
* Eventually, I want to move roll the glheader.h file into this.
*
- * The OpenGL SI's __GLimports structure allows per-context specification of
- * replacements for the standard C lib functions. In practice that's probably
- * never needed; compile-time replacements are far more likely.
- *
- * The _mesa_*() functions defined here don't in general take a context
- * parameter. I guess we can change that someday, if need be.
- * So for now, the __GLimports stuff really isn't used.
- *
* \todo Functions still needed:
* - scanf
* - qsort
- * - bsearch
* - rand and RAND_MAX
- *
- * \note When compiled into a XFree86 module these functions wrap around
- * XFree86 own wrappers.
