[fpc-pascal] Lack of 'volatile' a serious issue. Any other such caveats?

Actually, it is the other way round: FPC is not interested in
optimziations taking a lot of time and mainly having a purpose in
artifical benchmarks. E.g. spending a lot of time in optimizing globals
variable access is for real world programs normally not really usefull
as the number of global variables in good programs is really low.

Of course, if you are interested in highly optimized code squeezing out
every processor cycle, you do not care about compilation times and you
are only interested in embedded programming, FPC is not the right tool
for you and this will not change.
