that cpp file is not including the correct headers, some are missing, earlier today there was a reduction to a simple "sdk_precomp.h" include, but that's not good enough.
I will have a look at it tomorrow, if Morton hasn't beaten me to it ;-)
[EDIT] for me it's now tomorrow ;-)
committed, probably the include paths are not 100% correct in the autotools build ?? ...
I think the sdk dir should be added, can someone confirm or proof the opposite ?
