Actually I was thinking the opposite: that this file was way too big and
should be broken up into smaller more manageable pieces.

In this usage, I think all is referring to all MADs. ib_types.h supports
SM and SA MADs and some other MADs but not all MADs.

It is currently used by management and utils. utils/linux-user could be
moved.

What would be the new proposed location for this ?

Why is Windows 1.1 and not 1.2 compliant ?

Another issue is that ib_types.h requires some complib things too.

Perhaps but is this a real requirement ?
