[texhax] Macro Problem

I am currently writing some macros related to the glosstex-package
and have tracked down my problem to the following line:

This line works as expected (output nothing or "false", depending
on parameter #4):

    \ifx#4\empty \else false \fi

This line doesn't work since it produces "false" always (independent
of parameter #4):

    \ifx#4\empty true \else false \fi

Thanx in advance for your help.
