Here's a front end for cc that I use constantly. It acts exactly like cc but
links things to use shared libraries. I posted an earlier version last
year, but the -L option handling turned out to have a bug in it. Also, this
version links things into the fast-loading -F (0413) format -- thanks to Dennis
McCunney for passing me the incredibly obscure little hack necessary to get
that to work (believe it or not, you trigger it with the order of the link
arguments).
# ccs -- compile with shared libraries for AT&T 7300 or 3B1 (version 1.2)
# Written to replace cc by Eric Raymond {cbmvax!snark!eric}
CC=/bin/cc # Standard C compile program
LD=ld # Standard loader
OSTART=/lib/crt0s.o # Standard startup code
PSTART=/lib/mcrt0s.o # Monitored startup code for profiling
# Find shared version of libraries
if [ -f shlib.ifile ]
then
SHLIB=shlib.ifile # Use local customized version if it exists
else
SHLIB=/lib/shlib.ifile # Otherwise use standard ones

You can call this as ccs or copy it to /usr/bin/cc. It will give you cleaner
cleans, whiter whites, build strong bodies twelve ways, and make your programs
load and execute maybe 10%-15% faster.
