Thanks for tracking this down, great detective work!

Technically, I'd consider 1.0.12 to be the current official MSYS DLL, as 
1.0.13 is still in Proposed. I'm glad I waited long enough for issues to 
crop up before making it official. A big thank you to all the testers.

I wonder why it doesn't show on Cygwin, tough.

Sure.

Great, feel free to upload as you see fit.

I'm interested to know if it solves a failure I was having when building 
  gcc 4.4.3 for mingw, also related to gawk. I had to fall back to 
1.0.12 for the build to continue.

Perhaps it would be wise to rebuild MSYS gcc and binutils afterwards, 
just in case.

Sounds reasonable.
