Yes, with that patch applied the build proceeds far beyond that point (still running). Thanks for the quick fix! Gerald

With your new patch, it works for me again using `mawk` (cf.

Hi Gerald:
Thanks for reporting this issue, I just realized multidimensional
arrays are gawk extensions, could you try the attached patch to see if
it can resolve the issue?

Subject: [PATCH] options: Prevent multidimensional arrays
Multidimensional arrary is gawk extension, and we accidentally
introduced that in recent commit[1].

gcc/ChangeLog:
* opt-read.awk: Drop multidimensional arrays.
* opth-gen.awk: Ditto.
