Are you wanting to do this inside the program?  If not, then Raúl's  
suggestion is what you want.  "time gcc -c x.c" will spit out the  
time that the gcc took.  If you have lots of modules, put them in a  
make file and just to "time make"

I thought you wanted to do it from inside the program.  Like when it  
first starts up, it would tell you how much time it took to compile.

__TIME__ returns a string (or it IS a string actually).  You could  
put one at the top of each file.  Plus have an extra file that is  
compiled at the end of the list of files that has another.  e.g.  In  
each file do:

this_file_cpp_time = __DATE__ " " __TIME__;

(where "this_file" would be different for each file).

Put all of these in a table maybe.  Then have a routine go through  
the table of strings and convert them to time structures -- see  
strptime et. al. for info.

 From the time structures you can do your computations.

Hope this helps...
