Sure.  From top to bottom:

* Added {$IFDEF FPC} block to turn on {$MODE DELPHI} and the PUREPASCAL
define.
* Fixed CallerAddr's declaration to use {$IFDEF PUREPASCAL} instead of
{$IFDEF CLR} around the "assembler" statement.  This just makes it match
the implementation block.
* Added "unix" to implementation uses clause when appropriate, needed
for fpgettimeofday.
* Added NativeInt type declaration in the implementation section for
cases where it isn't available or is declared incorrectly (Delphi 2009
and earlier, FreePascal 2.4).
* InitPerformanceCounter/QueryPerformanceCounter (unix) use FreePascal's
fpgettimeofday rather than libc's gettimeofday (in $IFDEF).
* Stubbed out CheckMethodIsNotEmpty for FPC.  The byte read was causing
a crash, but I didn't look into it further, and I did this before I
realized TMethodEnumerator was broken, so this change might not be
necessary.
* Implemented FPC-specific version of TMethodEnumerator.Create.
* In CreateRegistry I removed the non-CLR codepath, so it always uses
ParamStr(0) instead of calling GetModuleFilename.  At least under Delph
7+/Kylix 3, ParamStr(0) already uses GetModuleFilename, rather than
returning the real command line parameter, so there /shouldn't/ be a
change in functionality here.

The CreateRegistry change is the only one that could conceivably affect
existing code, though I don't know how.  Everything else is in an
{$IFDEF FPC} or similar block.

I haven't gotten DUnit's own tests to compile under FreePascal yet, but
the Abbrevia testsuite works fine.  All of the tests still pass under
Delphi XE2.
