glibc test time regression after gawk update

[arnold@skeeve.com]

Hi.

I suspect that the problem is line 34 in the script:

	value = gensub(/^(INF|NAN|inf|nan)/, "+\\1", 1, val)

There was a bug in gensub with \N escapes that has been fixed.
Can you try with https://www.skeeve.com/gawk/gawk-5.4.0d.tar.gz?

FYI, feedback on this ASAP would be really good, as I am planning
to release 5.4.1 this week.

Thanks,

Arnold
