IMO compiler messages slow down compilation a lot.
How do you know this, did you benchmark or is it just your opinion?
When messages are not really output (prevented by message level...),
then a lot of procedure calls and string operations can be avoided, when
the message preparation is bypassed at all.
verbose.Message1 ff. could check the level (and exit accordingly) prior to
any further work.
MayBeLoadMessageFile could be moved into Msg2Comment in most cases, and again
a quick check (or inline) can prevent calling this subroutine at all.
Sounds reasonable to me, but wether it will speed up compilation is
another question. Anyway, simply write a patch, could be a nice excercise
to get started with compiler development.
