1) Its build system uses a weird configure script with ancient
references to AIX, Solaris 4.x and Vxworks.
2) Yes, variables do carry over, but we don't mess around with those
variables at all. The top-level caller is the only one that fiddles
with those variables.
3) The writers of the original Makefiles don't use implicit rules and
instead use CFLAGS instead of CXXFLAGS which is an epic fail for
all... CFLAGS =~ CXXFLAGS, but CXXFLAGS !~ CXXFLAGS.
So in conclusion: the makefiles are junk.
HTH,
