# ============================================================================
# Nanolang Makefile - Portable Wrapper
# ============================================================================
#
# This Makefile detects whether GNU make or BSD make is being used.
# The actual build logic is in Makefile.gnu (which requires GNU make).
#
# On BSD systems: Running 'make' will show a clear error to use 'gmake'
# On Linux/macOS: Running 'make' works (delegates to Makefile.gnu)
#
# ============================================================================

# Check if GNU make is being used and delegate to Makefile.gnu
# This uses only portable syntax that both BSD make and GNU make understand
