[1.7] cygwin2 performance issue during compilation with autotools

[kiorky]

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 default.
I tried to reinstall the cygwin environment a bunch of times, as it could be a
'pebcak' problem. It must not, afterall, because the slowness is always there.

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 /usr/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 applications
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.
