Postgresql - multibyte

hello,

I have a problem during compilation of Postgresql 7.1
I configure it with --enable-multibyte=LATIN2 --enable-odbc --enable-locale
Everything goes OK.
Then I type gmake, and after a while of compilation I get an error message
like:

gmake[4]: Entering directory
`/export/home/root/instalacje/postgresql-7.1/src/backend/utils/mb'
