I eventually fixed my problem. This bit from config.log raised my 
suspicions:

configure:7233: checking for ar
configure:7249: found /usr/local/binutils-2.19.51/bin//ar
configure:7259: result: ar
configure:7368: checking for as
configure:7384: found /usr/local/binutils-2.19.51/bin//as
configure:7394: result: as
configure:7503: checking for dlltool
configure:7519: found /usr/local/binutils-2.19.51/bin//dlltool
configure:7529: result: dlltool
configure:7561: checking for ld
configure:7587: result: 
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld.exe

I can't say why ld.exe is found at /usr/i686-pc-cygwin/bin/ld.exe (it's 
not even in my PATH) or even how it got there. There are also copies of 
ar.exe and friends in the same directory, but for some reason, they're 
not getting picked up. Seems mysterious.

After nuking /usr/i686-pc-cygwin/bin (so that the binutils-2.19.51 
version of ld.exe would get picked instead), the build completed 
successfully. I can now build and run executables under cygwin with gcc-4.5.

I still don't know who is at fault for my original problem.
