problems with libiconv into kernel

[Nilton Jose Rizzo]

Hi all,

    Last night, I has tried to put in my kernel config the libiconv with this
knobs from LINT:

options         CD9660_ICONV
options         MSDOSFS_ICONV
options         UDF_ICONV
options         LIBICONV

but this results int this error:

         ^

*** Error code 1

Stop.
make: stopped in /usr/src/sys/amd64/compile/VALFENDA

What am I doing wrong? My svn version is 255531

TIA,
