NaN or divisions by 0.0 as floating-point exceptions (FPE). This is a problem with some libraries which expect that e.g. "NaN * 3.0" is NaN or "4.0 / 0" is INFINITY.
- The (strange) default behavior can be changed by setting the control word of the FPU. This is done by assigning $133F to this register via Set8087CW() in delphi. In FPC it was not available for a long time but now it is. OpenGL12.pas contained an own version of Set8087CW() which was totally wrong because the important asm-directives (fclex and fldcw) were missing so it was not of any use. Hence it was removed from the unit so it does not hide the correct FPC version anymore.
- This should fix some EDivByZero exceptions in floating-point expressions (as with projectM).
