Add Cc: to -current list.
This seems to be "varargs.h" problem. It seems that all C source
which use varargs.h and va_dcl become error on GCC 3.3.1 system.
Please try compiling following varargs.h sample program.
--------
#include <varargs.h>
void test(va_alist)
va_dcl
{
va_list args;
char *fmt;
va_start(args);
fmt = va_arg(args,char *);
va_end(args);
}
--------
The result is as follows:
--------
motoyuki@sakura[38] % cc -c varargs_test.c
varargs_test.c: In function `test':
varargs_test.c:3: error: syntax error before '...' token
varargs_test.c:8: error: syntax error before "__builtin_varargs_start"
--------
I think following patch to /usr/include/varargs.h is needed
to solve this problem.
