In C++ incremental rebuilds are simple as you compile each file

Compiling multiple modules at once provides lots of speedups as you do
not have to reparse and analyze common/mutual imports, but on the
downside it cannot be parallelized that well.
I wish I knew how Delphi was compiling things because it is by far the
fastest compiler I have ever tried. It compiled individual files as well
but not into obj files but some dcu files and it used them if source
wasn't changed when compiling sources that depended on that module.
Yeah, in time of Delphi 6 I thought that Delphi wasn't as serious as C++
(don't remember compiler version exactly) because Delphi compiles so
fast comparing to C++. C++ was cool that time in my eyes because I can
see it was doing something cool and of course very serious)) Delphi was
really as fast as lightning and it was not interesting.
