The install.pl script understands that it does not know what options are 
needed for local text compilations.  That is why it pauses with stern 
words about FDEFAULT.SH.

The Makefile for XAS is another problem.  The editor we use on that file 
knows to change the name of the compiler but does not know how to change 
the options.  When the rest of the compile is done (or from a separate 
window) edit the Makefile and do a make in $YSERV/XAS/ directory.

I build aips on my personal machine with the gnu compilers
primate<518>$ /usr/bin/g77 --version
GNU Fortran (GCC) 3.4.6 20060404 (Red Hat 3.4.6-4)

$SYSLOCAL/FDEFAULT.SH has

       COMPSWIT="-c -fno-automatic -fno-globals -Wno-globals -Wimplicit 
-Wall"
       case $COMPILER in
#                                       GNU g77
          *g77*)
               OPT0="" ; OPT1="-O"
#                                       Options for GNU 2.95.3
#             OPT2="$OPT1 -fexpensive-optimizations -funroll-loops"
#             OPT2="$OPT2 -fstrength-reduce -frerun-cse-after-loop"
#             OPT2="$OPT2 -fforce-mem -fforce-addr -fcaller-saves"
#                                       These are probably dangerous...
#             OPT2="$OPT2 -ffast-math -funroll-loops"
#                                       Options for GNU 3.2+
               OPT2="-O2"
               OPT3=$OPT2 ; OPT4=$OPT3 ; OPT5=$OPT4 ; OPT6=$OPT5
               OPT7=$OPT6 ; OPT8=$OPT7 ; OPT9=$OPT8
               NOOPT=$OPT0
#             DEBUG="$DEBUG -fdebug-kludge"
               ;;

CCOPTS.SH in $SYSLOCAL has

COMP="-c -O3 -fomit-frame-pointer -funroll-loops 
-I/home/primate/AIPS/31DEC09/INC -D_FILE_OFFSET_BITS=64 -DHAVE_LINUX_GLIBC"

LDOPTS has nothing special.

Makefile
# LIBDIRS_LNX64    = -L/usr/X11R6/lib64 -Xlinker -rpath -Xlinker 
$(LIBR)/INTELCMP
LIBDIRS_LNX64    = -L/usr/X11R6/lib64

#LOCALOPTS_LNX64    = -O2 -axWPT
LOCALOPTS_LNX64    = -O2

#CC_LNX64    = /opt/intel/Compiler/11.0/074/bin/intel64/icc
CC_LNX64    = /usr/bin/gcc

(Note that my mail tool breaks up the long lines)
