bfd.info failing in binutils 2.32

["Paul Edwards" <mutazilah at gmail dot com>]

I am trying to build binutils 2.32 on Windows cygwin,
like this:

export PATH=/usr/bin
set -o igncr
export SHELLOPTS
./configure --target=i386-pc-mingw32 --with-sysroot --disable-nls --disable-werror
make


I am getting these errors:

else \
 rc=$?; \
 $restore $backupdir/* `echo "./bfd.info" | sed 's|[^/]*$||'`; \
fi; \
rm -rf $backupdir; exit $rc

It says that it can't find elf.texi etc, but they are there:

C:\devel\binutils-2.32\bfd\doc>dir elf.texi
Volume in drive C is OS
Volume Serial Number is 4274-E68B

Directory of C:\devel\binutils-2.32\bfd\doc

2019-07-03  12:33               318 elf.texi

              0 Dir(s)  155,928,330,240 bytes free

Any idea what I'm doing wrong?

Thanks. Paul.
