Looks like it's due to this code in source/windows/winmain.c:
p = thisfile+strlen(thisfile) - 4;
if (strnicmp(p, ".exe", 4) != 0)
strcat(thisfile, ".exe");
I have absolutely no clue why it insists on adding a .exe extension. It
doesn't make sense at all. The code has been there before I resurrected
PyInstaller.
I can try removing it but I'll commit it tomorrow -- I don't have Visual
Studio handy now.
(Which BTW remembers me that I should really get the bootloader
compilation fixed! There's absolutely no reason why it still needs VS71
and VS60; it would work with any VisualStudio or MinGW right now).
