I'm working from the May 13, 1988 draft of the C pANS. In the header file, the v[fs]printf() function prototypes use the va_list type, but va_list is not defined anywhere in . The synopsis shows the need to #include both and in order to use v[fs]printf(), but what about #include'ing in a program which doesn't use these functions? The prototype would then be an error, right? Also, section 4.1.2 (the v[fs]printf() functions are in 4.9.6.[789]) states "Headers may be included in any order; ...". In order for the declaration to work, must be #include'd first. The standard also seems to imply that header files do not include each other. Is this the case? Do I have an outdated draft of the standard?
