I just discovered that this doesn't have to do with a new release of Racket, but some other dependency that Racket must be using (GCC?) that recently broke our ability to compile Racket, including Racket 6.11, the current Racket in Guix. I can't build it, and the error is the same kind of error as what I was getting with 6.12: Error [GCING] 1780 in ./../src/number.c: Function minus_zero_p declared __xform_nongcing__, but includes a function call at __signbitf128.
