I am sorry to have to trouble you again but I looked in 'config.site'
(I take it that you mean 'config.site' where you say 'site.conf') and
this is what I found with respect to CFLAGS and FFLAGS:
# Debugging and optimization options for the C compiler.
# Use this to specify CFLAGS for the version of the C compiler specified
# above. If unspecified, defaults to "-g -O2" for gcc, and "-g" in all
# other cases.
# Options for the FORTRAN compiler.
# Use this to specify FFLAGS for the version of the compiler specified
# above. If unspecified, defaults to "-O2" for g77, and "" otherwise.
So I think this means that the default values for both gcc and g77 are
already set to "-g -O2".
Would specifying them anyway make any difference or am I misunderstanding
