I really would have love to investigate why it is slow; but atm, i have no =
more
ideas ...

For the only remark done far from now, i don't have any duplicates in PATH =
but
cygcheck must be bugged or it finds informations setted elsewhere than in
environment and that i'm not aware of. The install is clean, and barely def=
ault.
I tried to reinstall the cygwin environment a bunch of times, as it could b=
e a
'pebcak' problem. It must not, afterall, because the slowness is always the=
re.

There must be also another bug with the 'gcc' and 'cpp' not found because i=
 have
the gcc-4 packages installed and 'cc' and 'cpp' and 'gcc' are there, in /us=
r/bin
eg.
$ which gcc
/usr/bin/gcc


So, cygwin2 is a big stopper now. 6min on cyg1, 30 on cyg2. 5x slower. If i
translate that to running applications, it can significate that the applica=
tions
could be also 5x slower if they use the same functionalities which are used=
 by
the build systems (fork()?).
They have been installed the same way except the target directory, so, even=
 if
things can change between releases, i must have reproduced the bug somehow.
