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.
Error [GCING] 1958 in ./../src/number.c: Function double_is_integer declared
__xform_nongcing__, but includes a function call at __isinff128.
Error [GCING] 4050 in ./../src/number.c: Function double_fits_fixnum declared
__xform_nongcing__, but includes a function call at __isinff128.
