Report of experience:

The following happened:
-------- snip ----------
/src/cdkb20/newlib[2]$ ./configure -v --build=i386-pc-cygwin32
--srcdir=`pwd`
loading cache ./config.cache
checking for a BSD compatible install... /usr/bin/install -c

configure: error: source directory already configured; run make
distclean there first
/src/cdkb20/newlib[3]$ make distclean
make: *** No rule to make target `.././configure.host', needed by
`config.status'.  Stop.
-------- snip ----------

This command before configure did it:

/src/cdkb20/newlib[7]$ find . -name config.status -exec rm '{}' \;

Now, the following message appeared while running `make' in newlib:
-------- snip ----------
....

ar: illegal option -- .

make: *** [all-recursive] Error 1
-------- snip ----------

As you can see, ar has no option. But the line
	AR_FLAGS = rv
in newlib/Makefile helped temporarily:

-------- snip ----------
....

make[1]: o: Command not found

-------- snip ----------

	cd doc; make
or adding
	CC_FOR_BUILD = gcc
to newlib/Makefile did it.

As next I've started `make' in dir cdkb20:

Bingo! I haven't understood this. winsup/include is in the
search path and it contains a limits.h.

Any suggestion?
