[ emerges from some grubbing about in the gmake sources... ]
It looks to me like the bug in 3.80 is only triggered when "eval"
expands to a long enough string to trigger reallocation of the variable
buffer. (Ergo, the reason they didn't find it sooner was they only
tested on relatively short strings.)
I wonder whether the bug could be worked around if you did the iteration
on SUBDIRS in a foreach surrounding the eval call, so that each eval
dealt with only one subdir target. This would result in a bit of
redundancy in the generated rules, but that seems tolerable.
