@ -59,6 +59,11 @@ Here are some other suggestions:
6) explicitly add const qualifiers on parm passing in functions where parm
is input only (somewhat controversial but const can be #defined away)
7) when passing a va_list as an arg, or assigning one to another, check
for HAVE_VA_COPY, and use it if it exists.
reason: on some platforms, va_list is a struct that must be
initialized in each function...can SEGV if you don't.
8) discourage use of threads
reason: portability (also see architecture.doc)
