--- Comment #2 from sandra at gcc dot gnu.org ---
What is "it" that I'm supposed to change?

Note that things are going wrong in the libstdc++-v3/configure script well
before this comment (which appears at line 21812).

The initial empty-program link test is at line 3972.  The link test for
checking C99 stdio.h support is at line 16961.
