M2compiler-V1/build.sh

#!/bin/sh
#
# Builds the M2c compiler (step 2: scalars + MC64 backend).
# Requires GNU Modula-2 (gm2) and the Coco/R CR binary.
#
# Usage: ./build.sh   (from the project root)
#
# All sources live in src/ (grammar, frames, hand modules, generated
# scanner/parser/driver). Build objects (.o) stay in the project root
# (gm2 -I src drops them in the cwd); the binary links to ./M2c.
#
# Pipeline: src/M2c.atg -> src/M2cS/M2cP/M2c (.mod)
#           -> gm2 -fiso -I src -> ./M2c
#
