Here's the diff that I applied:

It is not compatible with GCC 2.95 because the new

typedef __builtin_va_list __va_list;

only happens on GCC 3.0 or above.  That's what the __GNUC_PREREQ__(3,0)
test is doing.  If the compiler is older than GCC 3.0, the old definition is
used.  As for it doesn't work, I bootstraped GCC 3.3 with the above diff in
place which used the 2.95 for the first stage compile without problems.
