# of ordinary ANSI-C programs, or to `cc', `cxx', `cpp' or similar
# if you want to treat CWEB as a system of C++ programs.  Your
# compiler should be able to distinguish between the two forms
# according to the source file extension.  Even with ANSI-C programs
# it is strongly recommended to use C++ compilers, because of the
# much stricter checking of type conversions and module interfaces.
# For highest portability, all of the extra features of C++ are
# avoided in the CWEB system, thus using something like C--.
