Sorry, I have not read this page for a while.
KILL_NOTIFY in WIDGET_BASE was added recently in 0.79.5.
CATCH in XMANAGER is missing, I'll add it in the next snapshot.
These errors come from an unfortunate coincidence. I have added signed bytes to FL, with the conversion function SBYTE (an analog to BYTE). CMSVLIB uses an array named SBYTE with subscripts SBYTE(...), which results in calls to the conversion function in FL. The easiest solution is to rename all instances of SBYTE in CMSVLIB to something else, eg. XBYTE.
