Yeah, I suspected that much. I was just surprised to see this
problem since I have tested the build system on a wide range
of installations (including very ancient ones) and I find it hard
to believe that new versions of bash would regress to disallow
this syntax.

But a quick glance through the p1003.2-d11.2 standard from 1991 shows
that the 'for x in ; do...' syntax is unspecified (although in my opinion
quite natural). On the other hand 'for x in ... ; do ; done' generates
an error which is a bit inconsistent if 'for x in ; do ...' is accepted
as a valid syntax.

Anyway, I have added the workaround.
