Hi Andy,

Hrm, it's odd that the new version doesn't fail for you.

I see no other error messages just repetitions of broken pipe message on 
some of the man pages it is working its way through. Some man pages work. 
Some don't. I stripped down the makewhatis script to just the awk portion 
(attached man.awk) and ran some tests as if it was being invoked by the 
makewhatis script and was able to reproduce the error (attached gawk.test)

I just assumed it was gzip complaining about the broken pipe given it is 
trying to unzip the compressed man page and the reader of stdout must've 
closed stdin. I'm not that familiar with gawk.

The distro is CRUX which has is simple source-based distro ref: 
http://crux.nu. I've attached the Pkgfile showing the configure/make 
process that built 4.1.1 and scrounged the git repo for the 4.1.0 Pkgfile. 
Nothing changed but the version.A

gawk is compiled as a 64-bit elf
  $ file /usr/bin/gawk
  /usr/bin/gawk: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
  dynamically linked (uses shared libs), for GNU/Linux 2.6.39, not
  stripped

And linked:
