Dan, I have to thank you for this suggestion. Building the current
(22.0) thunderbird was failing for me with the same failure that Cary
reported. This is on a 9.1-RELEASE amd64 system. I also tried building
with devel/clang but that was then failing elsewhere. Manually compiling
the troublesome file using the reported command but with the (dual!) -O3
flags removed - leaving the remaining (two!) -O2 flags - succeeded and
then the remainder of the build completed without further errors.

Thanks again for providing that info.
