Since upgrading to sys-apps/gawk-5.0.0, the makewhatis cron script in /etc/cron.daily now emits warnings (12 of them for me) of the following form: awk: cmd. line:130: warning: regexp escape sequence `\"' is not a known regexp operator Since these are emitted from a cronjob, they get emailed to me. Presumably they will be emailed to me every day henceforth until this is fixed. The error appears to be at line 363 of /usr/sbin/makewhatis: sub(/\\\".*/, ""); # Trim pending comments My semi-educated guess would be that the backslash before the double-quote character in the regular expression should be removed, as it is superfluous. Evidently the new version of Gawk warns about the unneeded backslash.
Unfortunately, sys-apps/man upstream appears to be dead. I suggest to switch over to sys-apps/man-db because at the current state it's quite likely that we will treeclean sys-apps/man
I was also experiencing the daily awk(1) email from makewhatis(1) in sys-apps/man. Per suggestion from Polynomial-C, I simply did `emerge --verbose --ask sys-apps/man-db`. The emerge unmerged sys-apps/man and merged sys-apps/man-db. I expect this solved the issue for me.

I confirm that removing the backslash before the double-quote character in the regular expression at line 363 of makewhatis script solve the problem. So a simple patch with a condition relative to >=sys-apps/gawk-5.0.0 can fix it.
