*cmiscdat.c - miscellaneous C run-time data

*
*Purpose:
*       Includes floating point conversion table (for C float output).
*
*       When floating point I/O conversions are done, but no floating-point
*       variables or expressions are used in the C program, we use the
*       _cfltcvt_tab[] to map these cases to the _fptrap entry point,
*       which prints "floating point not loaded" and dies.
*
*       This table is initialized to six copies of _fptrap by default.
*       If floating-point is linked in (_fltused), these table entries
*       are reset (see input.c, output.c, fltused.asm, and fltuseda.asm).
