Hi Jan,
good job, I was always wondering why it wasn't available for windows, I
am going to give it a try ... :-)

Hi,
For those building on Win32, it might be interesting that I've extended the
ccache [http://ccache.samba.org/] to deal with MSVC. I've done it during our
Novell HackWeek [http://idea.opensuse.org]; I hope you'll enjoy it as much as
I enjoyed the hacking on that ;-)
It is easy to use, instead of 'guw.exe cl.exe', you'll use 'guw.exe ccache.exe
cl.exe' in your CXX environment variable after having sourced the
environment. To see the ccache statistic, use ccache -s. You can override
the directory where is the cache stored by exporting CCACHE_DIR="c:
\where\you\want" Should you find any bugs, please send me patches :-)
I've not measured the speedup too much yet, but it was >20% in vcl compared to
non-ccache run, the penalty of the initial fill of the cache was like 17%
[compared to non-ccache]. Would be great if someone did a measurement of the
entire build.
The patch and the binary:
