Add NO_C99_FORMAT to support older compilers.
The NO_C99_FORMAT macro allows compilers that lack support for the ll,hh,j,z,t size specifiers (eg. gcc 2.95.2) to adapt the code to avoid runtime errors in the formatted IO functions. Signed-off-by: Ramsay Allan Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <junkio@cox.net>
