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.

Solaris (x86 and SPARC) is also broken in various ways: for example, the "sun"
preprocessor macro is no more defined.  Why do we need strict ANSI exactly?


This patch (or the earlier one) is also breaking a build of my MIPS
cross compiler.  On CentOS 5.11 (yes I know that is old) I can build a
cross compiler where the executables are x86_64 objects but not when
they are i386 objects (i.e. when using -m32 to build GCC).  The error
is duplicate atoll definitions (one in read-rtl.c and one in stdlib.h).

I may be mistaken but think when you moved the atoll check from
AC_CHECK_FUNCS to gcc_AC_CHECK_DECLS you needed to change and
read-rtl.c because gcc_AC_CHECK_DECLS sets HAVE_DECL_ATOLL instead of

I'm sorry. I totally forgot about autoheader...

I'm testing this one now. Would you mind giving it a try?

Steve has a valid point here and my update, see below, fixes that. Is this ok for trunk as well?

I tested on amd64/i386-freebsd and on x86_64 Gnu/Linux and also build in progress on i686 Gnu/Linux (CentOS).
