Does someone here know? I have a copy of Knuth volume 3, and am willing to look it up, but I don't know what the algorithm that I'm looking for is. (I could read the grep source code, but I figure it's easier to ask you. :-) > Is #error portable all the way back to older non-standard compilers? No. However, #error is portable to C89 and later. Grep already assumes C89 and later, so it's OK to use #error now.
