hniksic(a)srce.hr said: You're right. I haven't. And to get xemacs to compile, I don't need to (since either Fred's suggestion or using an older version of math.h will accomplish that). I'm not familiar enough with xemacs code to make positive suggestions about what to do. What I try to do (and the reason I read and post to this list) is to serve as a potential user with a particular configuration (MkLinux) that's got a reasonable installed base and where there's a lot of interest in using XEmacs. For that community (as well as most others), XEmacs should eventually build out of the box. I'm just reporting as much as I can about a way in which that assumption fails for this particular configuration, in the hopes that you or others on this list will find time to make life easy for MkLinux users.
