Details:

Octave fails to build with Intel Compiler.
I'm using 3.8.2 release + patch from
https://savannah.gnu.org/bugs/index.php?43171

It crashes like this

icpc ... -c numeric/SparseCmplxCHOL.cc -o
numeric/.libs/numeric_libnumeric_la-SparseCmplxCHOL.o
In file included from /usr/include/cholmod_check.h(70),
                 from /usr/include/cholmod.h(95),
                 from ./util/oct-sparse.h(73),
                 from numeric/sparse-base-chol.h(27),
                 from numeric/SparseCmplxCHOL.h(27),
                 from numeric/SparseCmplxCHOL.cc(28):
../libgnu/stdio.h(948): error: declaration is incompatible with previous
"getchar" (declared at line 538 of "/usr/include/stdio.h")
  _GL_CXXALIAS_SYS (getchar, int, (void));


And the same thing for putchar and vprintf functions.
Such error pops up for any file that uses ./liboctave/util/oct-sparse.h

The problem is somehow similar to the
https://savannah.gnu.org/bugs/index.php?43171 and
https://savannah.gnu.org/bugs/?43063, it occurs (imho) because of the
following include chain

oct-sparse.h -> cholmod.h -> extern "C" { ... cholmod_check.h ... } ->
stdio.h



As a temporal fix i've modified line 23 in stdio.in.h adding "defined
CHOLMOD_H"

#if defined __need_FILE || defined __need___FILE || defined
_GL_ALREADY_INCLUDING_STDIO_H || defined CHOLMOD_H
