This patch ports 5 new applications to the stubdom makefile structure for inclusion into stubdom domains. While these are required for vtpm-stubdom and vtpmmgrdom they could be used with other stubdom applications. -libgmp 4.3.2 -openssl 1.0.0a -polarssl 0.12.1 -berlios tpm_emulator 0.6.1 -vtpm_manager (from the tools directory) Signed off by: Matthew Fioravante

Is this something the compiler can be clever about, or is the only solution to not use 'long double'? /Henrik On...

I'm observing that base::sum(x, na.rm=FALSE) for typeof(x) == "double" is much more time consuming when there are missing values versus when there are not. I'm observing this on both Window and Linux, but it's quite surprising to me. Currently, my main suspect is settings in on how R was built. The second suspect is my brain. I hope that someone can clarify the below
