Here's a testcase:

$ cat >tc.c <<EOF
#include <windows.h>
#include <stdio.h>

int main()
{
  char buf[512];
  
  GetModuleFileName (NULL, buf, sizeof (buf));
  puts (buf);
  return 0;
}
EOF

$ gcc -mno-cygwin tc.c

$ ./a
\\?\C:\cygwin\home\brian\testcases\native-argv0\a.exe

You can also reproduce this just by running "tclsh".  The problem is
that tcl is a native app and uses the w32api directly, and so these
native paths leak into it and it's un-equipped to use them properly.
