gcc produces wrong code when optimizer (O1 O2 or O3) is used.
The c-source showing the problem is generated by the flex lexical scanner.
Applies to gcc versions 3.0.4, 3.3.5 and 3.4.4 (and maybe others not tested).
Tested on Debian/Intel platforms only.
On gcc 2.95 and multiple former versions of gcc, the problem does not occur.
