Hi, I just found out, that Ruby 1.9 does not install the version.h in its header includes directory. An extension I wanted to compile for 1.9 tried to include version.h in order to check against RUBY_VERSION_CODE for #if macros and the like, which caused the compilation to fail. Is it an oversight, that version.h isn't included anymore or is there some other (preferred) way to find out the version at the compilation stage of an extension? -- Florian Frank
