I agree that we ask for a big modification 2 days before the release, but 
I think that it is really important.

i'm also happy with that. It's also used in ither projects that I know.

using the same names than the C99 types is good too (or close to)
int8, uint8, etc...
I don't think that the '_t' of the C types is usefull.

maybe we can use something like glib, and adding an 'x' prefix : xint8, 
xuint8, etc...

For me, there is no problem. I can change evas and ecore. And in 1 day, we 
can modify xcb-utils et xcb-demo. And if a (perl, sed ,etc..)script can be 
written to change that automatically, it will be even simpler.

Do you think that Josh can handle that in time ? He is our xsl master, so 
he is the one that will do that quickly.
