- I've been waiting for this one to come up. I had the problem about 3 weeks
- ago, composed a post for this group with the above sort of info, went to post
- it and my NNTP server had timed out. I then spent literally ages trying all
- the compiler debug switches to get some/any kind of useful output. After
- greping through .5 Mbytes of compiler parser/syntax analyser output (oh what
- a hero I hear you cry), I still hadn't a clue. In a fit of inspiration I read
- the code and noticed the comments about compilers having problems with casts
- for the COPY_FUNCTION emunerated type. I've never programed in C before so
- the following fix is a pure hack, no flames please.
-
- BTW, I went to post this code fragment after I'd found the fix but my NNTP
- server timed-out and lost the post again so I gave up in despair, lets hope
- this one get through!
-
- In the switch statement at the end of gdevmem1.c, replace the copy_left
- and copy_right emunerations with their actual numeric values (4 and 0).

- The problem has been logged with DEC, its a brain dead compiler. Funnily
- enough this all compiles fine on Alpha OSF/1 :-) but then I get all those nasty
- run time segmentation violations ... any kind soul out there got fixes for this
- one?
