libtool 1.4b and $CC = g++ and cygwin32

[Kevin B . Hendricks]

Hi,

When building the latest aspell (C++ code) using libtool we found that the 
following snippet of libtool (from libtool.m4) fails when using cygwin32


    extract_expsyms_cmds='test -f $output_objdir/impgen.c || \
      sed -e "/^# \/\* impgen\.c starts here \*\//,/^# \/\* impgen.c ends 
here \*\// { s/^# //;s/^# *$//; p; }" -e d < $''0 > $output_objdir/impgen.c~
      test -f $output_objdir/impgen.exe || (cd $output_objdir && \
      if test "x$HOST_CC" != "x" ; then $HOST_CC -o impgen impgen.c ; \
      else $CC -o impgen impgen.c ; fi)~
      $output_objdir/impgen $dir/$soroot > $output_objdir/$soname-def'


It fails when $CC is defined to be g++ and not gcc

(when you try to compile impgen.c with g++ it barfs with alot of non-ANSI C++ 
error messages).

Thought you might like to know.
