Hello Giulio,
I've obtained the (expected) result: no standard include path is included.
Before posting that I'd like to have proper guidelines to post onto this
mailing list.
The site says:
Please no top posting
Please wrap lines at 75 characters
Please no HTML, only plain text e-mails. Even the most hopeless
MUAs have a switch to turn off HTML in message composition, please use it.
Please DO NOT SHOUT!!!!!! in e-mails, particularly when asking for
help. This tends to make people awake and grumpy.
Please do not send screenshots when plain text pasted into your
message would suffice.
Actually I've made a mistake and wrapped the last mail to 80 chars.
Should I be doing that or the guidelines are obsolete?
Thanks,
Simone
