there are many configure scripts out there that still check for things

non-parallel nature of configure scripts).
often configure scripts take longer to finish than compiling the source
code itself on decent machines with multiple cpu cores.
having an option like --assume-c99 could provide a shortcut so all
checks like
- have stdint.h
- have snprintf()
- etc
and for posix
- sizeof int == 4
- have select()
- etc
These assumptions are unsafe, esp. on non-mainstream architectures/OSes,
which only partially implement c99.
E.g. it's not that uncommon to find toolchains for embedded platforms
which implement most of C99, but with sizeof int != 4 or without "select()".
