    When a function is declared and named with the blank identifier, only
    the syntax is checked.  This patch modifies the parser to add a dummy
    node for each function declaration with a blank identifier name that
    will be type checked like any function declaration.
    
    Fixes golang/go#11535.

(The previous iconv-related commit missed the config/iconv.m4 change.)

Original description:

This is the second in a series of patches to make a build with an
in-tree GNU libiconv work as designed.

Currently GDB is the only toolchain component which actually uses an
in-tree libiconv.  This patch modifies the common AM_ICONV to use an
in-tree libiconv when present and not already provided by libc.
(GDB's workaround uses an in-tree libiconv even when libc provides
iconv(3); I'm not sure when or why that would be desirable.)

config/ChangeLog:
2015-08-24  Yaakov Selkowitz  <yselkowi@redhat.com>

	* iconv.m4 (AM_ICONV_LINK): Use in-tree libiconv when present.
