Thanks for reporting the problem. Please try the attached patch against Gawk master. The ChangeLog entry is a bit optimistic, as it is assuming that the patch works (and if it works, I would like to install the relevant changes into Gnulib and into glibc, so that at that point the ChangeLog entry will be correct).

Alternatively, if you want a smaller patch you can arrange for __builtin_expect to be a no-op on compilers that do not support it, as Bruno suggested.
