Decimal float and the Cygwin build of GFortran.



I have build GFortran under Cygwin configuring with:

             ./configure --prefix=${prefix_dir} \
                         --enable-languages=c,fortran \
			 --enable-bootstrap \
		         --enable-libgomp \
		         --enable-threads \
		         --enable-sjlj-exceptions \
		         --enable-version-specific-runtime-libs \
		         --enable-nls \
		         --enable-werror \
		         --enable-checking=release \
		         --disable-libmudflap \
		         --disable-shared \
		         --disable-win32-registry \
		         --with-system-zlib \
                         --without-included-gettext \
		         --without-x 


The build gives, a few times, this warning:


---------------------------------------------------
...
checking for valgrind.h... no
configure: WARNING: decimal float is not supported for this target
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
checking whether make sets $(MAKE)... yes
...
---------------------------------------------------

A few months ago this did not happen (same building procedure).


So, have you an idea about this ?


TIA,

  Angelo.
