cp: define a FIXME macro that leaves a sclp message There are far too many fixmes in the code. Sadly, the compiler simply discards them. This usually isn't an issue until one accidentally hits a "weird" bug which just turns out to be an unhandled (but documented) case in another part of the code. Using a macro instead of a comment will let the compiler string-ify the text, and then at runtime use SCLP to print it out. This will immediatelly point at problem areas. So, keep an eye on SCLP from now on :) Signed-off-by: Josef 'Jeff' Sipek <jeffpc@josefsipek.net>
