I'd like to avoid adding more and more machine specific #ifdefs to that
I wonder if we could do something cleaner by letting the va-* files provide
an override for the type of __builtin_va_alist.
For example, we might consider having the va-* file conditionally define
__BUILTIN_VA_ALIST_TYPE or some similar variable to the right type, then
do something like:
#define __BUILTIN_VA_LIST_TYPE int
[ ... includes of various va-* files ... ]
#define va_dcl __BUILTIN_VA_ALIST_TYPE __builtin_va_alist; __va_ellipsis
A va-* file that wanted to override could do
#define __BUILTIN_VA_LIST_TYPE long
Or something along those lines.
