windows installer, third try

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Dear PARI developers,

I am working again on the windows installer.

I try to add support for gphelp (?? under gp) by using the mingw perl binary.
The only problem is for GP to find the path of the components.

My current attempts is at 
<http://pari.math.u-bordeaux.fr/~bill/Pari-2-6-0.exe>

Please try something like 
??sin
??bnfinit
??
and see whether it displays the help text.

Cheers,
Bill.
