I think this is safe to close as won't fix and not a true compatibility bug. No one has stepped up to "fix" this, no updates in over 3 years. The text returned by the computer function is informational at best. If we did try to be completely Matlab-compatible with the returned strings, what should we return for 32-bit Linux? 64-bit FreeBSD?

If your use case requires the return value to be exactly what Matlab returns, it's easy enough to write your own computer.m function file that returns the value you want based on ispc, isunix, etc.

According to

"There are still a number of differences between Octave and Matlab, however in general differences between the two are considered as bugs."

It seams an issue to me. I noticed the different behavior while using a ML derived code. Though it's not an issue to me since I can replace the 'computer' call by 'ismac' or 'ispc' I felt that I should report this case.

I don't think this is a compatibility issue.

Octave runs on many more OS's than Matlab, and can be built to run on Window's natively,  on mingw, or Cygwin.

Are you using "computer()" for a specific purpose?

On Windows the command 'computer' prints

octave-qt.exe:1> c = computer
c = i686-pc-mingw32

on ML

c = computer
