All,
This patch restores bootstrap on i386-*-freebsd*.
The build was failing after the introduction of -std=c++98
configure/build flag. The -std=c++98 enables strict_ansi and on FreeBSD
the libc function atoll is not defined for this.
But the configure always stated atoll available.....
A bit debugging showed, to my understanding now, the AC_CHECK_FUNCS only
checks it a func is available, not more. While the gcc_AC_CHECK_DECLS
really recognises the build flags and tells me that atoll w/o std=c++98
is available and with std=c++98 it is not available.
So, the below patch addresses this and restores bootstrap on FreeBSD.
Ok for trunk?
Thanks,
Andreas

* configure.ac: Move the atoll check from AC_CHECK_FUNCS to
gcc_AC_CHECK_DECLS.
* configure: Regenerate.
