Yes, nevertheless the RTL needs to be adjusted for this, because the 
heap manager uses the HeapAlloc function from kernel32.dll and not the 
Visual C RTL.

The big work of a WinRT port of FPC is exactly this substitution of API 
calls. Adding a new target to the compiler and the build utilities is 
easy. Implementing the RTL is the hard one and you'll have to do that no 
matter whether you do a "quick and dirty" port or a real one. In both 
cases you'll need to research the correct function to use and the 
correct way to pass in or retrieve data.
