No, you are wrong here.
GNU Pascal doesn't claim to be a drop-in replacement for Turbo Pascal.
It is designed to be a portable compiler, running on a variety of
hardware and operating systems. Although it accepts a large subset of
the Borland Pascal syntax, it (currently) doesn't come with the units
you are familiar with.
Some things which are legal in Borland Pascal (direct memory access)
are not portable at all and will probably never appear in GNU Pascal.

The construction is perfectly legal, as long as you provide a CRT
unit. ;-)
No, serious: work is being done to write some borland replacement
units. A BGI replacement for djgpp already exists. We still need
volunteers.

Yes.
Or assembly, if you prefer that....
If you invoke it with the --automake switch it will automatically
build units if necessary (like Borland does)

If you mean GCC object code and libraries: yes.
Simply declare them as "external; C". That's all.
