sig_atomic_t is defined as a long and thus is 64-bit on arm64. For some reason its limit was incorrectly specified as a 32-bit number. This had the unfortunate side effect of causing gnulib to override most of the definitions in stdint.h. On CheriBSD this breaks all software that uses gnulib in annoying and hard to debug ways. Technically updating the limits might be an ABI change, but these defines are largely unused (the only use in tree is in the libc++ test suite where it's use an assertion that will fail due to this bug). Further, since the underlying type remains the same, we're just increasing the range of values a paranoid program might use.
