— Don't use %I on Windows
Older versions only understand I64. So only use I64 where appropriate
and drop it entirely where not. (user: js, size: 16873) [annotate] [blame] [check-ins using] [more...]

— Better fallback asprintf() implementation
Instead of trying if it's C99 compliant and falling back to a 64 KB
buffer if it is not, resize the buffer in powers of 2 until it fits.The problem is that some implementations that are not compliant with C99
don't just return -1 for a length of 0, but actually crash (e.g. HP-UX). (user: js, size: 16630) [annotate] [blame] [check-ins using]
