Tested Unstable Revisions
From Free Pascal wiki
This article lists revisions from the unstable branch of Free Pascal (2.1.1) that were tested and found to be working on some platforms. This is mainly useful for people interrested on features only available on 2.1.1, like internal linker, or support for many platforms, like Windows CE and Windows 64-bits.
