restFP and saveFP errors in phred/phrap installation

I realize this question is tangential to staden, but I can't find a
phred/phrap discussion group. I could really use some help installing
phred and phrap (and Consed). I am a relative Unix newbie who is
trying to install  phred, phrap and consed on my G4 Powerbook running
10.2.8. After decompressing  the tarballs in /usr/local, I cd to the
phred directory and type ‘make' as per the installation instructions.
The result is the following error:

viewPhred.o  writeData.o  writePhd.o  writeQual.o  writeRunInfo.o 
writeSCF2.o  writeSCF3.o  writeSeq.o -lm
ld: Undefined symbols:
restFP
saveFP
*** Error code 1

Stop in /usr/local/phred.

I should mention that I have installed gcc3.3 using the Apple
August2003 updater.

One hint came from the installation instructions for the program:

Apple OS X.
   -----------

     a) If phred does not link under OS X, you may need to modify the
        'Makefile' in this distribution by changing the line with

          CLIB= -lm

        to

          CLIB= -lcc

     b) If the C compiler is not installed on your system, you may be
        be able to obtain it with the 'development tools' from the
        Open Source 'Darwin' distribution.

Unfortunately this did not fix the problem. I just got the following:

al.o  writeRunInfo.o  writeSCF2.o  writeSCF3.o  writeSeq.o -lcc
ld: can't locate file for: -lcc
*** Error code 1

Stop in /usr/local/phred.


I also searched for suggestions via google and various discussion
groups, and similar errors seem to occur when others are trying to
build unix programs under 10.2. The consensus seems to be that
libraries are not being correctly linked. The most helpful tip I came
across was the following from the Apple unix-porting discussion group:

Link with either /usr/lib/libcc_dynamic.a or /usr/lib/libgcc.a,
depending on
your needs.  It's always handy to do:

%cd /usr/lib
%nm -o lib* | egrep 'T saveFP'

for example.

I tried 
%cd /usr/lib
%nm -o lib* | egrep 'T saveFP'

and got the following:

It seems like I need to link to libcc_dynamic, libcc_kext or libgcc
(or perhaps all three). Two questions:

Do I need to link all three libraries or just one? I'm thinking libgcc
is the one I need.
How do I link these libraries for building? Please give precise
instructions.

One other question: The programs' authors suggest the following
makefile edit:
Edit 'Makefile'.

   In particular, you may want to modify CFLAGS for the highest
   level of optimization offered by your compiler.

Here is the relevant makefile section:

# UNIX specific definitions (default)
#
CC= cc
CFLAGS= -O -DANSI_C $(LXFLAGS)
CLIB= -lcc

How exactly do I modify CFLAGS?

Thanks in advance for your help.
