   Hello,
     I was wondering if it is possible to make a .lib in djgpp 
   v2.0 and include it by useing 

   #include "whatever.h"

   ?

     currently to speed up compile time i just use .o files but 
   they aren't as nice as a .lib in turbo c.  

Yes.  The DJGPP distribution includes the UNIX ar utility which maintains .a
archive files which are the library files used by the DJGPP loader ld.  So, you
can create libraries as below:


gcc -c unit1.c unit2.c unit3.c

ar -r /mylibdir/libunits.a unit1.o unit2.o unit3.o

and use the library as:


gcc -ounitprog unitmain.c -L/mylibdir -lunits

Obviously all of this can be put into makefiles.  BTW: GNU make, also
distributed with DJGPP, knows how to maintain and extract from ar libraries and
how to check time dependencies of object files in a library.
