Rename without-mingw-progs to with-cross-bootstrap, since it now disables additional checks that are problematic for cross-compilers. When cross-compiling a toolchain targeting cygwin, building cygwin1.dll requires libgcc. However, building libgcc requires the cygwin headers to be installed. Configuring cygwin requries the mingw-crt libraries, which require the cygwin headers to be installed. Work around this circular dependency by making the --with-cross-bootstrap configure option skip cygwin's configure checks for valid mingw-crt libraries. Cygwin will still properly link against these libraries if they exist, but this allows configure to succeed even if the libraries have not been built yet. Since the mingw-crt libraries only require the cygwin headers to be installed, this allows us to successfully configure cygwin so that we can only install the headers without trying to build any libraries. winsup/ChangeLog configure.ac: rename without-mingw-progs option to with-cross-bootstrap configure: regenerate winsup/cygserver/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate winsup/cygwin/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate Signed-off-by: Peter Foley <pefoley2@pefoley.com>
