Problems with Cygwin-1.7.8 (or snapshot) and TeXLive 2010

[Angelo Graziosi <angelo dot graziosi at alice dot it>]

After I flagged these problems [*], I chose to do a clean reinstall of 
TeXLive 2010 (TL2010). After installed its packages (> 2000!), TL2010 
installation proceeds with its post-install actions, mainly generating 
all format files. The installation is done as 'root' (administrator), 
but the format files are created for all system users (as it should),

-rw-r--r-- 1 root root 20760  3 mar 16.33 foo.fmt

Now, with recent snapshot (say >= 20110215, including the one released 
today) this does not occur any more,

-rwx------ 1 root root 20760  3 mar 16.33 foo.fmt

so, when a simple user builds his/her latex documents the fmt file are 
regenerated in a local directory under HOME.

JUST substituting the snapshot DLL with that of 1.7.7, restores the 
right behavior (like on GNU/Linux). With 1.7.8 it fails completely, as 
described [*].

At first sight, I thought that was caused by my mistaken in installing 
the snapshots, but I followed literally FAQ and installing 1.7.7 as a 
snapshot fixes the problems. So it seems a regression in 1.7.8 series.

Ciao,
Angelo.
