By Landon Curt NollBuilding calc in 3 easy steps:    1) Look at the makefile, and adjust it to suit your needs.       Here are some Makefile hints:	   In the past, some people have had to adjust the VARARG or	   TERMCONTROL because the Makefile cannot always guess	   correctly for certain systems.  You may need to play with	   these values if you experience problems.	   The default compiler used is 'cc'.  The default compiler flag 	   is '-O'.  If you have gcc, or gcc v2 (or better) you should use	   that instead.   Some compilers allow for optimization beyond	   just -O (gcc v2 has -O2, mips cc has -O3).  You should select	   the best flag for speed optimization.  Calc can be cpu intensive	   so selecting a quality compiler and good optimization level can	   really pay off.    2) build calc:	make all    3) test calc:	make checkFor further reading:    LIBRARY    	explains how programs can use libcalc.a to take advantage 	of the calc multi-precision routines.      help/todo	current wish list for calc    CHANGES	recent changes to calc    BUGS 	known bugs and mis-features        help/full	full set of calc documentationIf you find bugs (better yet if you have bug fixes); or if you havesuggested changes (better yet if you have patches), send them to:    dbell@canb.auug.org.au    chongo@toad.com		    {uunet,pyramid,sun}!hoptoad!chongo
