Re: inetutils 1.9.5 rc1 on Cygwin

On Cygwin 2.9, there are two kinds of compilation errors:

1)
Making all in libinetutils
make[2]: Entering directory 
'/home/bruno/inetutils-1.9.4.50-9410/build-cygwin64/libinetutils'
  CC       tftpsubs.o

directory

                       ^
compilation terminated.
make[2]: *** [Makefile:1572: tftpsubs.o] Error 1

The file /usr/include/arpa/tftp.h existed in Cygwin in 2006. But in Cygwin 2.9,
it no longer exists.

2)
<config.h> is not found.

config.h has been generated in the top build directory. The problem is that
Automake has generated a target for creating e.g. 'ping.exe', but since
the Makefile wants to create 'ping', 'make' uses a built-in rule that
ignores AM_CPPFLAGS.

I think the problem is here: ping/Makefile contains
  all: all-am
  all-am: Makefile $(PROGRAMS)
  PROGRAMS = $(bin_PROGRAMS)
  bin_PROGRAMS = $(ping_BUILD) $(ping6_BUILD)
  ping_BUILD = ping
  ping6_BUILD =

ping_BUILD ought to be 'ping$(EXEEXT)', not just 'ping'.
I think the bug is in am/enable.m4 line 25.
