I may be putting my foot in my mouth, but I want to say that Rtools changed at 2.15 from mingw to gcc. I would check that you have the most recent version of Rtools installed, make sure you have the right directories in your path environment variable (which also changed, I believe), and make sure you use the default tool chain in Mkrules.local if you set it.
I think the 'giving credit where credit is due' dept requires an update there.
All builds of R under Windows in recent years have used GCC ('GNU Compiler Collection') and GNU binutils (for the assembler, linker, ...). All 64-bit Windows builds have used the ports developed for the MinGW-w64 project, as well as their runtime ('libc', 'libm' and more, including headers).
Prior to R 2.14.2 we used for 32-bit Windows the ports from the Mingw.org project and their runtime. We now use the 32-bit versions from MinGW-w64.
Erin had libgomp.spec missing. There are MinGW-w64 toolschains out there with it missing, but the master sources for the toolchain I compiled does have it.
The OPENMP setting in src/gnuwin32/MkRules.dist should not need changing if the correct toolchain is used (and that the binary distributions manage to get built with the default setting is some confirmation of this).
