I looked at the top level configure and make scripts and it looks to me like they use the environment variables, with one exception noted below:

configure:

ac_ext=c
ac_cpp='$CPP $CPPFLAGS'
ac_compile='$CC -c $CFLAGS $CPPFLAGS conftest.$ac_ext >&5'
ac_link='$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5'
ac_compiler_gnu=$ac_cv_c_compiler_gnu

configure.ac:

# The following may not give the most helpful messages if there is no
# C compiler at all, so I will do a simple pre-check based on a limited
# number of plausible choices.

Makefile.in:

COMPILE = $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) \
	$(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)


If I'm not mistaken everything looks correct, except for the 2 if-statements. What do they need to be changed to? Do I make a bunch of diff files, or use reinplace?

There are also config/make files in /csl, /csl/fox, and /psl, which I need to check.
