This chapter deals with speed of compilation and linking under DJGPP, and how they could be improved.
If you already know whether the compiler or the linker is the slow
part, go to the appropriate section; if not, add
-v to your GCC
command line and run it again. With the
-v switch, GCC will
print all the programs it invokes, and you will be able to tell which
one is taking most of the time.
