php-gettext: msgfmt.exe dll problem

[inul]

I got an error message when I use msgfmt.exe command

"The procedure entry point libiconv_set_relocation_prefix" _ could not be located in the dynamic link library iconv.dll"

Does anyone know what dll is missing / might be outdated?

I used
* msgfmt.exe from gnu.org gettext-tools-0.12.1.bin.woe32.zip
* iconv.dll from php-4.3.1
* libiconv.dll from gnuwin32.sourceforge.net (I tried version 1.7 and 1.8)

I've spent 2 days trying to figure out the problem (I'm new to Windows).

TIA.
