any chance to fix this?

Code:

Procedure Depth()
  !EXTRN _PB_Screen_Depth
  !MOV eax, [_PB_Screen_Depth]
  ProcedureReturn
EndProcedure

Procedure Screen()
  OpenScreen(640, 480, 16, "")
EndProcedure

have you tried this?

Code:

Import ""
_PB_Screen_Depth
EndImport

Import works for variables too (and TB should be able to handle it)

this code works (and is easier to port to x64 as there's no need for change [unsure if this symbol has the same name in x64]):

Code:

Import ""
PB_Screen_Depth
EndImport

Procedure Depth()
  ProcedureReturn PB_Screen_Depth
EndProcedure

Procedure Screen()
  OpenScreen(640, 480, 16, "")
EndProcedure

Though I will take a look into the extrn issue; but if you prefer the ASM way, just comment out the !extrn line; TB can figure out that its an external symbol by itself.
