	* libgst/oop.c: Allocate large objects from fixedspace.
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have been superseded respectively by the Autoconf-provided ones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.
