Incorrect double quote handling in command line parameters on Win32 and Win64

Summary

When using FPC programs compiled for Win32 or Win64 every double quote toggles the "quoted" status. This means that it is impossible to pass a double quote inside the parameters on the command line.

System Information

• Operating system: Windows
• Processor architecture: x86, x86-64
• Compiler version: trunk
• Device: Computer

Steps to reproduce

compile the example project and run with the following command line: testdoublequotes.exe """Bob was here"""

Example Project

program testdoublequotes;
{$mode delphi}
var i: integer;
begin
  writeln('ParamCount:', ParamCount);
  for i := 1 to ParamCount do
    writeln('Param(', i, '):', ParamStr(i), ';');
end.

What is the current bug behavior?

Program outputs: ParamCount:1 Param(1):Bob was here;

What is the expected (correct) behavior?

ParamCount:1 Param(1):"Bob was here";

Possible fixes

All other platforms, including WinCE and Win16, seem to handle escaping double quotes and using single quotes instead of double quotes. I will attach the patch I used to bring Win32 and Win64 parameter handling in line with WinCE and Win16. syswin.inc.p1.diff
