I tried to build boost-trunk on a NetBSD system. The following patch is required to get most of the way through (the math lib has additional errors). Because these changes are completely dependent on identifiers of NetBSD, I cannot see how they might negatively affect anything else. What is the procedure for getting this patch applied? Thanks for your help.
