[cvsnt-dev] Bug in cvsnt kills Codepage Translation under HPUX

Dear Tony,

Some day ago I have written:

The problem is not caused by a wrong "expat" version, but caused by the
fact that cvsnt is not linked properly with the GNU "libiconv" library
under HPUX. Therefore the codepage translation from HP-ROMAN8 to UTF-8
fails and the data fields in the "fileattr.xml" file are not filled,
since cvsnt tries to convert usernames etc. to UTF-8 before storing in

Instead of the GNU libiconv functions (libiconv(), libiconv_open(), ...)
the HPUX iconv functions (iconv(), iconv_open(),...) are linked in.
This is caused by a "#define bug" in diff/unicodeapi.c and

You define:

But the parameter "HAVE_LIBICONV" is nowhere defined, therefore
"LIBICONV_PLUG" becomes defined, which prohibits later the mapping from
iconv() -> libiconv() etc. in <iconv.h>.
The cvsnt "configure" script generates only a "config.h" file, in which
the parameter "HAVE_LIBICONV_OPEN" is defined, in case GNU libiconv is found
on the system.

Renaming HAVE_LIBICONV to HAVE_LIBICONV_OPEN in "unicodeapi.c" and
"Codepage.cpp" solves the problem: The correct GNU libiconv routines are
the codepage translation from HP-ROMAN8 to UTF-8 is carried out and the
"fileattr.xml" files are generated correctly.

Best regards
