Differences between Win32 FASM .inc files

Question

What is the difference between the win32a, win32ax, win32axp, win32w, win32wx, and win32wxp .inc files in Flat Assembler? I tried to find it in the FASM documentation but I couldn't...

Thanks in advance, The ChristonianCoder

There are six headers for 32-bit Windows that you can choose from, with names starting with win32 followed by either a letter a for using the ASCII encoding, or a letter w for the WideChar encoding. The win32a.inc and win32w.inc are the basic headers, the win32ax.inc and win32wx.inc are the extended headers, they provide more advanced macroinstructions, those extensions will be discussed separately. Finally the win32axp.inc and win32wxp.inc are the same extended headers with enabled feature of checking the count of parameters in procedure calls.
