CFLAFS and CC

[Bessiere Julien]

Hi, 
        i'm trying to install shapelib in the process to install
        MapServer
        but...
        I have this message:

        cc -g shptest.c shpopen.o  -o shptest
        
        As said in the INSTALL file, i have to set CFLAGS and CC.
        But i don't know what to write.
        For the moment it's : CFLAGS  =       -g
        I'm on fedora core 5.
