I think lots of people are busy. :) I glanced at it and still have it on my todo list, but have many things on said list. Can you expand on the problem you have with inffast.S? Also, it might read better if the flow of the Makefile is: .if ${MACHINE_ARCH} = "i386" . if ${CPUTYPE:Mpentium*} . if ${CPUTYPE} == "pentium" || .. .PATH: . else .PATH: . endif SRCS+= match.S CFLAGS+= ... . endif SRCS+= inffast.S CFLAGS+= ... .PATH: ... . if ${CPUTYPE} == "pentium-mmx" CFLAGS+= ... . endif .else SRCS+= inffast.c .endif That is, merge the two i386 sections into one section. -- John Baldwin
