Sorry for the late reply, but I am not subscribed to the list and missed
this post through the gmane interface.
Actually, when I try to execute python through the symlink in a *cmd.exe*
I get this kind of requester:
--------------------------------------------------------
| Sottosistema MS-DOS a 16 bit X |
|--------------------------------------------------------|
| |
| Prompt dei comandi - c:\cygwin\bin\python.exe |
| La CPU NTVDM ha incontrato un'istruzione non valida. |
| CS:06ea IP:21f1 OP:65 63 69 66 69 |
| Scegliere "Chiudi" per terminare l'applicazione. |
| |
| ------ ------ |
| |Chiudi| |Ignora| |
| ------ ------ |
--------------------------------------------------------
saying that the CPU has encountered an invalid instruction, which I took as
an indication that the file was not recognized as an executable.
The title of the requester refers to the "16 bit MS-DOS subsystem" and I have
no idea of what this means. This is on Win2000, perhaps on WinXP it is
different, I don't know. As noted in another post, Windows style paths are
not a problem with cygwin when properly quoted.
