(...) Sorry... I was going to recommend the same thing last night, but got sidetracked (it has been a tough two days to be a Duke basketball fan.)

(...) I think the compiler was generating incorrect code. I'm no gcc expert, but the asm macros looked OK to me, and besides, why should the macro work in one compiler version & not the other? FYI, I fixed it by compiling the source to an assembler (...) (24 years ago, 26-Mar-00, to lugnet.robotics.rcx.legos)

(...) Because there were some decisions made as to what "incorrect" macros were and weren't by the egcs/gcc teams.

(...) IMHO it is better anyway to use pure assembly files when generating code like memcpy (which is completely in assembly here). Call them memcpy.S, and you won't have the problem of accidentially removing them. With this you can use 'c' style (...) (24 years ago, 26-Mar-00, to lugnet.robotics.rcx.legos)

(...) I don't know if Markus would approve, but it might be worthwhile to do this and put it in to CVS so that 0.2.4(?) would be compilable with 2.95.x. Does anyone have the time/skill to do this?

(...) I've posted an update which includes memcpy.s, memset.s (even though this didn't seem to cause a problem, I thought best to keep things consistent) and Makefile (so it doesn't delete *.s for target clean).
