[Bug libstdc++/22339] New: iconv functions not found by libstdc++v3 configure

[mjscod at gmx dot de]

The iconv functions (iconv, iconv_open, and iconv_close) cannot be found by
configure because it doesn't include "iconv.h" where iconv is defined as
libiconv, iconv_open as libiconv_open, and iconv_close as libiconv_close.

I suggest changing the iconv functions to:

1. check if iconv.h exists
2. when checking for iconv, iconv_open, and iconv_close then include the iconv.h
header, otherwise use the explicit prototype.

I meant: "changing the iconv function detection to:". Sorry.

Is this in reference to _GLIBCXX_USE_ICONV?

That is only useful for the codecvt specializations that use iconv. As of 4.0.0,
this is in libstdc++-v3/include/ext/codecvt_specializations.h. 

Or is this in reference to runtime testing? That looks different.

However, what you are suggesting is still easy to do.
