GPC supports the uses statement, but AFAIK, the crt unit hasn't been
ported.

GPC works just like gcc.  You can do
gpc foo.pas -o foo.exe  -> produces foo.exe, no .o
gpc -c foo.pas          -> produces foo.o

You can call c functions from pascal, as long as you give it a
prototype:
function my_c_func(x:integer):integer;c;
I haven't tried the other way around.
