Yes, and often, until it gets fixed in CVS. :-)

In re-reading that post, the solution that has worked for me is to patch fixinc.sh. In that script is 
a list of targets where fixinc is not built. I have put the avr and m68k targets in this list and 
everything *seems* to be fine. I don't know if this would be the correct solution, but AFAICT the 
avr and m68k don't seem to need fixinc.

This doesn't seem to be related; this post talks about issues with memcpy and family. The 
issue with building fixinc for host=mingw is the POSIX function calls that are in the fixinc 
source; this is related to the collect2 issue as there are also POSIX calls in the collect2 source 
and hence problems with building for host=mingw for collect2.
