As you can see from my mail, it needs only the integer version of it,
but I *did* test both.

Of course adding also the non-CF version of the std lib to the project
file:
---
...
filler.c (filler.h)                                                                    
ahccgemf.lib                                                                           
ahcctos.lib                                                                            
ahccstfi.lib                                                                           
ahccstd.lib 
---

fixes the issue as that includes the missing function, but I'm
afraid the non-CF versions of mul & ldiv aren't CF compatible...?

(After that project file change AHCC CF version started to bus error though,
and I cannot for some reason get it working anymore although I removed all
intermediate files. :-/)


Depending on link order, AHCC might also include all the rest of the std
functions from that instead from the CF version of std lib also listed
in the project file.  I'm assuming AHCC linker takes the function from
the library containing the function that is listed first in the project
file.

It's all explained in the AHCC manual.

Adding that doesn't seem to help either (I don't use any math
functions or defines so that was expected).

I completely understand there being bugs in AHCC versions.
Henk is just a single person and I don't think he has a (private)
test suite for it.

There are bugs in nearly all the releases (I've reported Henk
bug(s) in every release I've tested), it's just luck that you
haven't happened to hit them. :-)

Those bugs aren't a problem though as Henk typically responds
very quickly with a fix and so far I've never seen the same
bug, they're always new ones / ones found with some code
(e.g. bug in my own code) I haven't tested earlier.
