One complication with C and C++ is that some variables have file
scope. Even if none do, the compiler has to be able to compile them,
and so tends to keep data in memory (or backing store) through the
whole file. Many functions in one file compile slower than they would
as separate files.


Fortran compilers traditionally reinitialize just about everything on
an END statement, before starting the next program unit. I believe
the standard has been changed, but in the past compilers did that so
well that a comment after the last END would start a new program unit.
The result was many error messages, such as missing END statement, and
duplicate MAIN program at link time.
