[bug #15757] circular variable_set_list causes hang on SunOS

[Ab Wilson]

Follow-up Comment #6, bug #15757 (project make):

Further to...

The structure of these makefiles is such that make has a global view of
everything, but if I type make with no arguments it will build all the
targets and their prerequisites for the current directory (including those
prerequisites from outside the current directory). If I do this in the
directory which was failing I don't see the problem but if I build the target
everything which depends on targets for the current directory the problem
occurs. This leads me to believe that it is not the particular combination of
rules for the directory which is causing the problem, but the shear overal
complexity of working with the dependencies for the whole source tree. Are
there any fixed sized buffers etc you can think of which may limit the code
size make can work with?
