GNUmakefile

# Self-contained GNU makefile for libparserutils.
#
# GNU make prefers GNUmakefile over the upstream netsurf-buildsystem Makefile,
# so plain `make` here builds libparserutils without that buildsystem.  This
# file is deliberately standalone — it touches nothing tracked and writes its
# output under build-gnu/ — so the commit adding it can be rebased cleanly.
# `make -f Makefile` still drives the original buildsystem.
#
# It builds a static archive: build-gnu/libparserutils.a
#
# The input filter uses the system iconv (glibc) by default; nothing extra is
# needed at archive time (iconv resolves when the final program is linked).
