fpc/bugs

This directory contains test files for various FPC bugs.
The most files are very simple and it's neccessary to check the assembler
output.

The first coloumn contains the file name. If the file name is indended,
the bug is fixed and the last coloumn contains the version where
the bug is fixed.

In future, please add also your name short cut, when fixing a bug.
