bc - GNU arbitrary precision calculator

Original author: Philip A. Nelson
Ported by Duncan Bowring using amiport (AI-assisted porting toolkit).
Project: https://github.com/bdgscotland/amiport

Cross-compiled with m68k-amigaos-gcc for AmigaOS 3.x (68000+).
Tested on FS-UAE with Workbench 3.1 (37/37 tests pass).

bc is an arbitrary precision calculator language supporting variables,
functions, and a C-like syntax. The -l flag loads a math library with
transcendental functions (sin, cos, arctan, ln, exp, bessel).

Usage:
  bc [-hlqswv] [file ...]

  bc                   Interactive calculator
  bc -l                Load math library (e, l, s, c, a, j functions)
  bc -q script.bc      Run script without welcome banner
  bc -c script.bc      Compile to bytecode (don't execute)

Examples:
  echo "2^10" | bc               Result: 1024
  echo "scale=10; 4*a(1)" | bc -l   Pi to 10 places: 3.1415926532

Replaces the ixemul-dependent bc 1.6 on Aminet (dev/gg/bc-1.6)
with a standalone noixemul binary. No runtime library dependencies.

Includes full source code (original POSIX and ported Amiga versions)
and PORT.md documenting every transformation applied.
