Subject [PATCH] Find libiconv
Date Sun, 21 Jul 2002 03:46:59 GMT
libiconv-1.8 installs a library with libiconv_open and friends
instead of iconv_open, and then uses iconv.h to #define iconv_open
to libiconv_open.  Because of this bizarre behavior, the standard
autoconf AC_CHECK_LIB can't find iconv.  This patch uses AC_TRY_LINK
instead.

I have tested it on NetBSD 1.5.2 with libiconv-1.8 straight from
ftp.gnu.org.  However, i'm neither an autoconf nor apr expert, so
this solution may not be correct.  I'm particularly unsure if LIBS
should be restored or not.
