And this is why it is usually premature optimization.. most people are 
using FPC likely for lazarus desktop apps, not game programming or fast 
graphics rendering, so no one cared about this bug/slowness until 
someone reported it..

Which is good that it was reported, to find a problem with FPC that was 
not noted before or that no one previously had any issues with.

But with that pascal game development web forum out there, it should 
have come up some time previously?  As there are game programmers out 
there using fpc, and there is andorra/zengl so what do they do? Work 
around the bug instead of fixing it at the source in the rtl/compiler? 
Swap in their own faster functions instead of replacing the rtl 
functions at the source level on fpc's svn server?

Often people will work around a bug instead of fixing it and reporting 
it because it's often hard to provide a test case that is small for the 
bug report to be accepted.
