gcc -ansi defines __STRICT_ANSI__ which hides prototypes for some
function needed by libstdc++-v3. Here are some examples one 
can find quickly:
	lrand48()  (recent report today about compilation errors)
	strtoll() and strtoull() are also used 
	maybe some others
They are detected at configure time without specifying -ansi.
So option -ansi may screw compilation of C++ sources. The same
about defining __POSIX_SOURCE__

All these functions are not hidden when I'm compiling using option
-ansi under Linux (I'm have glibc-2.2.3)
