Hi,
it's prepared for the musl. This version is based on the build logs
and original Makefile looked like this:
PROG= m4
CFLAGS+=-DEXTENDED -I.
SRCS= eval.c expr.c look.c main.c misc.c gnum4.c trace.c ohash.c \
tokenizer.l parser.y
MAN= m4.1
all: ${PROG}
parser.c parser.h: parser.y
${YACC} -d $< && mv y.tab.c parser.c && mv y.tab.h parser.h
tokenizer.o: parser.h
CLEANFILES+=parser.c parser.h tokenizer.o
include prog.mk
"include prog.mk" forces more mk deps etc. and it makes no sense for
only a few C files. Therefore the version which was sent is _ugly_,
but it _works_.
To add m4 to the toybox, you must remove the configure file, so don't
understand why you want to lose time...
btw: https://ohse.de/uwe/articles/aal.html
If you're not convinced, check how (hand-written) configure and
Makefile works in musl.
