[Bug libfortran/35471] libgfortran fails with nonstandard <complex.h>

Can't verify that the patch provided works.  After three attempts at a build
(one just by patching libgfortran.h followed by a "make", one by "make
clean-target-libgfortran" followed by "make" and one built from scratch in an
empty object directory), all fail in a way similar as this (can't show initial
make commands because they overflow my 10,000 line default conversation
buffer):

gmake is GNU make 3.81 (if not used, the build fails due to outdated make
unable to cope with features of newer make versions)

configured with

../gcc/configure MAKE=gmake --enable-languages=fortran

gmp 4.2.2 configure: ./configure
mpfr 2.3.0 configure: ./configure LDFLAGS=-L/usr/local/lib
