Note: The -Xp is relative to the current working directory. When
compiling a project the cwd is the project directory. That means
"../lib/fpc/2.6.3" won't work. You have to specify the full path
-Xp/usr/lib/fpc/2.6.3.

The bad thing about -Xp is that if the directory does not exist, there
is no error, no warning, no hint. fpc simply takes the default compiler.
