[X# 3] Problems with PTR type in Net 10

[cpyrgas]

Following snippets from the runtime, reporting errors when compiling for Net 10 (no errors when compiling for Net 4):

FUNCTION Empty(uValue AS PTR) AS LOGIC
    RETURN (uValue == NULL_PTR) // error XS0034: Operator '==' is ambiguous on operands of type 'ptr' and 'nint'

DEFINE F_ERROR :=  IntPtr{-1}

FUNCTION Start() AS VOID
LOCAL hfTo      AS PTR
? hfTo == (IntPtr) F_ERROR // error XS0034: Operator '==' is ambiguous on operands of type 'ptr' and 'nint'

LOCAL uValue AS USUAL
uValue := UIntPtr.Zero // error XS0457: Can't convert from 'usual' to 'nuint'. The possible conversions found are 'usual.implicit operator byte(usual)' and 'usual.implicit operator decimal(usual)'. You should try an explicit conversion.
local i64 := (UIntPtr)uValue as UIntPtr

Oh, I see you have now adjusted the runtime code to workaround those, Robert, same as with #1791. But shouldn't some of this still compile in Net 10? Especially the error in FUNCTION Empty(uValue AS PTR)

[RobertvanderHulst]

Yes, it should compile. But it was easier to adjust the code for now.

I have added implicit conversions from USUAL <-> UIntPtr to solve one of the issues.
The other issue needs to be handled by the compiler.

[cpyrgas]

Robert, I just checked, the line of code above

local i64 := (UIntPtr)uValue as UIntPtr

throws a runtime exception "Conversion Error from USUAL (OBJECT) to PTR" also in X# 2.

So probably this part of code wasn't working properly either before in X# 2
