Bad Universal headers or...?

Im trying to build mozilla 1.0.0 but it fails.
some projects generate errors while compiling.

But 6 mouth ago, i build version 0.9.5 without any problems.

I checked in mozilla.org if I need to update something but theres nothing
different since the last time i check.

Do I need to update something?
Some modules or the Universal Headers?

Thank you.

Eric.
