Subject: [PATCH 1/2] ext/gd: conflicting iconv_t typedef breaking the Solaris
 build.

The gd 2.4 sync guarded gdkanji.c's 'typedef void *iconv_t' fallback
with HAVE_ICONV_T_DEF, which the bundled build never defined. On
Solaris <iconv.h> declares iconv_t as a struct pointer, so it clashed.
Define HAVE_ICONV_T_DEF when <iconv.h> already provides iconv_t.
