0f26252376 + cgenmath with libc math functions. Faster than the routines in genmath 
and also have full double support (exp() only has support for values in
    the single range in genmath, for example). Used in FPC_USE_LIBC is
    defined
  * several fixes to allow compilation with -dHASINLINE, but internalerrors
    because of missing support for inlining assembler code

2af569745c * if currency = int64, FPC_CURRENCY_IS_INT64 is defined 
+ round and trunc for currency and comp if FPC_CURRENCY_IS_INT64 is
    defined

    currency -> float conversions

  * TODO: write FPC_DIV_CURRENCY and FPC_MUL_CURRENCY routines to prevent
      precision loss if currency=int64 and bestreal = double
