HsBaseConfig.h

/*
 * A stand-in for the HsBaseConfig.h that GHC ships with base, for the
 * benchmark corpus only.
 *
 * Eighteen modules in a Stackage snapshot include this header. The real one is
 * around nine hundred lines, almost all of it errno constants that no module in
 * the corpus refers to; what they do use is the HTYPE_ family, which names the
 * Haskell type corresponding to a C typedef and is substituted into type
 * declarations. Only those are defined here.
 *
 * The mapping below describes a conventional 64-bit Unix. Nothing is compiled,
 * only preprocessed, so the values need only be defined and expand to something
 * shaped like a type name. Written from the macro names the real header
 * defines rather than copied from it, so that this repository stays under a
 * single licence.
