[PATCH] Fix for PR c/57490

[Rainer Orth]

Hi Iyer,

>    First off, my sincerest apologies for letting this bug slip the cracks. I am attaching a patch that seem to work fine with the .i file that you have submitted in bugzilla for both C and C++. Please let me know if this fix works for you and if it is OK for trunk.

thanks for the patch.  I've just bootstrapped it on i386-pc-solaris2.10
and all an-if.c failures are gone.  That said, I wonder why we need the
separate pr57490.c testcase, which is practically a preprocessed version
of an-if.c with the HAVE_IO code removed.

I cannot approve the patch, though.

	Rainer
