[PATCH] build: don't use obsolescent AM_PROG_CC_STDC and AM_CONFIG_HEADER

> The Automake-provided macros 'AM_PROG_CC_STDC' and 'AM_CONFIG_HEADER'
> have been superseded respectively by the Autoconf-provided ones
> 'AC_PROG_CC' (since October 2002) and 'AC_CONFIG_HEADERS' (since July
> 2002).  Moreover, those obsolescent macros will be removed in the next
> major Automake version (1.13).  Stop using them.
>
> * configure.ac (AM_CONFIG_HEADER): Don't use this, ...
> (AC_CONFIG_HEADERS): ... use this instead.  While we are at it,
> properly quote the argument.
> * snprintfv/configure.ac (AM_PROG_CC_STDC): Drop this, the invocation
> to AC_PROG_CC is enough.
