The Gpm_Event data structure is not just used in the wire protocol, but returned to the application. I.e. for a C application: extern int Gpm_GetEvent(Gpm_Event *); For a Pascal application: function gpm_getevent(var event:Tgpm_event):longint; This means an application compiled using one version of the Gpm_Event data structure will not work on a system using another version of the Gpm_Event data structure. This means any application compiled on a non-Debian system transfered to a Debian system will break. Further, gpm.h is not really understandable for a Pascal compiler. It has its own gpm interface unit. Patching your gpm.h will work for C programs only (luckily for Debian that is a majority). That means compiling a Pascal program on a Debian system (Free Pascal is included in Debian), will cause the program to use the wrong gpm event data structure. Daniël Mantione
