[fpc-pascal] The unfortunate deprecation of GetTickCount

[Alexander Grotewohl]

It's deprecated by Microsoft. If I had to guess, it's likely not going 
anywhere until 32bit binary support in Windows is long gone.

Should you use GetTickCount on any Windows system that supports 
(natively) GetTickCount64? NO, not in new code.

That's exactly what deprecated means.

IMO compiling code targeting Windows >= Vista that has GetTickCount in 
it is no good.
