/usr/ccs/bin/ld: Unsatisfied symbols:
   libiconv (first referenced in java/parse.o) (code)
   libiconv_open (first referenced in java/parse.o) (code)
   libiconv_close (first referenced in java/parse.o) (code)
collect2: ld returned 1 exit status

I think what is happening is that the GNU version of
libiconv installed in /opt/gnu is not found because
the GNU iconv.h has "const" in the prototype for
iconv_open:

  extern iconv_t iconv_open (const char* tocode, const char* fromcode);

configure then detects the HP iconv in libc and as a
result we have

#define HAVE_ICONV 1
#define ICONV_CONST

in auto-host.h and

LIBICONV=

in the gcc/Makefile

However, gcc uses the GNU iconv.h header in the build.

I think the fix is for the configure test program to define
"const" to "" when it does its declaration checks with
a non ISO compiler.
