[ns] compilation problem.

["Wayne W. Szeto" <wwszeto@hopper.math.uwaterloo.ca>]

Hi all,

I have some problems "make"ing ns-2.1b8 (see below).  Compile failed on
line 107 of object.cc, and line 107 of object.cc is as follows:

102 void NsObject::debug(const char *fmt, ...)
103 {
104        if (!debug_)
105                 return;
106         va_list ap;
107         va_start(ap, fmt);
108         vprintf(fmt, ap);
109 }

does anyone know where is "va_start(...)" defined?  I couldn't find either
"va_start" or "__builtin_va_alist" in any of the files in the ns-2.1b8
directory/subdirectories.
