A sure sign that you have fishy code :)
I have lots of code, and never ever experienced such a thing.
I even can't remember when the compiler last gave me a problem; and I use it daily.

Most problems I experience today have to do with version management.

I'm sorry, but I do not share your focus on speed. I have many projects, 
some of them have more units than mseide does, and yet I never have to wait 
more than a couple of seconds. The only exception is the Lazarus IDE.

If you say that mseide only compiles with -B, I would suggest looking for 
strange dependencies inside mseide, if you want to reduce compile time...

I do not want to say that FPC does not need speed improvements, but I do suspect you 
will get faster results looking at removing the -B requirement from mseide...
