Weird diff format? It human readable! Use "patch" tool, Luke. Wink

See attachment.
I have no access to external SVN repository here.

I know it is human readable, I read it Wink

I'm just not used to see the "new-style context format". Also, I use 'patch' when I want to apply a patch, but I know for sure that some devs don't, since they don't have the GNU userland on windows. Most notably Mirek, who IIRC applies the patches in TortoiseSVN, which only understands unified diff format ('diff -u').

Build time reducing in 1.5-3 times per single C++ file depend on compiler.
Benchmarks performed on uppsrc/ide package in full debug.
First build was full, with all files included. For include all files in blitz batch their dates made equal.
Second build performed after touching 4 files (Assist.cpp, AutoSetup.cpp, idewin.cpp, idebar.cpp).
Third build (touched same files) executed only for Blitz.

Well, those numbers seem quite interesting. I must admit that they surprised me Smile

I will give it a closer look as soon as I have a little free time, hopefully over the weekend.
