Well it's often possible to temporarily 'fix' such issues by means of a
symbolic link to the right place; as long as it's limited in scope,
the use of an 'external' limits.h file shouldn't break anything ....?!

I would have thought there was an add-in package that would supply
the missing headers - surely we are not in Windows "hide system files"
territory ?

I don't know whether Ubuntu is missing the entire /linux subdirectory
or just the limits.h file, but just add the minimum required to get past
this obstacle, i.e. don't link to the /linux directory if you can help it,
just create an empty one (if missing) and add a symlink to the
existing limits.h file.

In this way the possible side-effects of using a 'foreign' file are
reduced, and you use as much as possible from the correct toolchain.

The above is *not* from direct Ubuntu experience, but I have made
'enabling' fixups in the manner described to get things to build
before now.

Mike
