Now that I added more > functions to font-lock-defaults nothing is highlighted anymore. You need to look for the actual error that causes this. Is there are relevant message in *Messages*? Maybe M-x jit-lock-debug-mode RET (along with enabling the debugger) could help as well. > I took a quick glimpse at font-core.el and font-lock.el but I could not > find where the regexp match limitations are set The limits would be in src/regexp.c BTW, instead of creating a monster regexp, maybe another approach is to use a simple regexp that matches any identifier in function position and then look up a table to see what kind of highlighting to apply to it (IIRC that's what we do in elisp-mode to highlight macro calls differently from function calls).
