In iterator/iterator_facade.hpp, there are a lot of template arguments that have names like "R1" and "D2". Unfortunately, these "all caps" tokens are fodder for collisions with macros. On i386-pc-solaris2.8, for some reason, "R1" is defined to be "9" (it's some kind of register identification macro) and so instead of: template < . . . , class R1, . . . > we get template < . . . , class 9, . . . > which, of course, doesn't work :) I've attached a patch against 1.31.0 (the trunk for this file) to fix this one file by adding "_type" to the end of all such all-caps names. I have not tested it very well. Perhaps there should be a policy to avoid names that are likely to collide with system macros? Just using mixed case (or lower case) is probably enough.
