rtems-source-builder with fortran support (--with-fortran option).<br>

As for my application I need fortran support, how can I fix this problem?<br>
As long I can see, all symbols that the compiler claims as undeclared<br>
are indeed declared and accessible in file<br>
~/devel4.12-i386.fortran/rtems<wbr>-source-builder/rtems/build/<wbr>i386-rtems4.12-gcc-6-20160609-<wbr>newlib-2.4.0.20160527-x86_64-<wbr>linux-gnu-1/gcc-6-20160609/<wbr>newlib/libc/include/ieeefp.h<br>
May be it's missing a symbol, e.g a proper value for LDBL_MANT_DIG ?<br>
<br>
Thank you<br>
