qdoc does not handle nested if-then-else statements corerctly

qdoc3 does not process the following code correctly..

/*!
\if defined(QTOPIA_PLATFORM)
\title Qtopia Release Notes (Platform Edition)
\section1 Qtopia Release Notes (Platform Edition)
\else
\if defined(QTOPIA_OPENSOURCE)
\title Qtopia Release Notes (Open Source Edition)
\section1 Qtopia Release Notes (Open Source Edition)
\else
\title Qtopia Release Notes
\section1 Qtopia Release Notes
\endif
\endif
...
*/

When QTOPIA_PLATFORM is defined, the following error is reported by qdoc3:

/usr/local/qtopia/qtopia-platform-4.2.3/doc/src/releasenotes.qdoc:14: Unexpected '\endif'

When QTOPIA_PLATFORM is not defined, no errors are reported.

Problem: If the outermost if-statement has an else-block that contains a nested if-statement, qdoc does not consume the correct number of \endif directives when the condition of the outermost if-statement evaluates to true.
