[fpc-devel] Tests in Delphi XE3 regarding Type Helpers

[Sven Barth]

Hello together!

Could someone with access to Delphi XE3 please compile and run the 
attached tests and provide me with the output of the test or (in case of 
an error) with the output of the compiler?
The tthlperrX.pas tests should not compile, so here I'd like to get the 
error messages.
The other tests should compile, so please try to adjust them until they 
do and report me any adjustments you made. If you can't get them to 
compile then please report me the errors you get with the initial test file.

Thank you.

Regards,
Sven
