possible libtool bug blocking builds of Cygwin setup.exe

[Shaddy Baddah <lithium-cygwin at shaddybaddah dot name>]

Hi,

I am having trouble building Cygwin setup.exe (regular 32bit on
32bit). I am finding that the build is hanging at the linking stage of
libgetopt++:

make[2]: Entering directory 
`/cygdrive/c/Users/shaddy/cygwin-home/workarea/cygwin-setup-build/libgetopt++'
  CXXLD    libgetopt++.la

Building with options I have deduced give me some debug:

$ make AM_DEFAULT_VERBOSITY=1 am__v_lt_1=--debug 2>&1 | tee -a build.log

I find (with confirmation from pstree), the build is hung in libtool:

make[2]: Entering directory 
`/cygdrive/c/Users/shaddy/cygwin-home/workarea/cygwin-setup-build/libgetopt++'
/bin/sh ./libtool --debug --tag=CXX    --mode=link g++  -Wall -Werror 
-Wno-uninitialized -g -O2 -version-info 1:1:0   -o libgetopt++.la -rpath 
/cygdrive/c/Users/shaddy/cygwin-home/workarea/cygwin-setup-build/inst/lib src/GetOption.lo 
src/Option.lo  src/BoolOption.lo src/OptionSet.lo 
src/StringArrayOption.lo  src/StringOption.lo
libtool: enabling shell trace mode
...
+ func_convert_core_msys_to_w32 .libs/
+ set -x
++ /usr/bin/sed -e 's/[ ]*$//' -e 's|\\\\*|\\|g;s|/|\\|g;s|\\|\\\\|g'


The code that it is stuck on is:

  func_convert_core_msys_to_w32_result=`( cmd //c echo "$1" ) 2>/dev/null |
    $SED -e 's/[ ]*$//' -e "$lt_sed_naive_backslashify"`

And I found the double-slash on the cmd to be problematic. If I
manually edit it out, the build continues (but only to a real build
failure, which I'll leave out for the moment).

I've attached the cygcheck.out from that build host, a Windows 8
computer. However, I also encountered exactly the same problem on a
Windows 7 computer.

Have I stumbled on a real problem?
