Arch Linux

Description: saving and loading data in hdf5 format (load -hdf5, save -hdf5) fails with the error message:
Warning! ***HDF5 library version mismatched error***
The HDF5 header files used to compile this application do not match
the version used by the HDF5 library to which this application is linked.
Data corruption or segmentation faults may occur if the application continues.
This can happen when an application was compiled by one version of HDF5 but
linked with a different version of static or shared HDF5 library.
You should recompile the application or check your shared library related
settings such as 'LD_LIBRARY_PATH'.
You can, at your own risk, disable this warning by setting the environment
variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'.
Setting it to 2 or higher will suppress the warning messages totally.
Headers are 1.8.12, library is 1.8.13
....

Using the suggested HDF5_DISABLE_VERSION_CHECK=1 (or 2) solves the problem, but is annoying. So, I tried to recompile octave but it fails with error message:
In file included from /usr/include/SuiteSparse_config.h:47:0,
from /usr/include/amd.h:46,
from ./util/oct-sparse.h:33,
from numeric/sparse-base-chol.h:27,
from numeric/SparseCmplxCHOL.h:27,
from numeric/SparseCmplxCHOL.cc:28:
../libgnu/math.h: In function 'int signbit(double)':
../libgnu/math.h:2576:1: error: conflicting declaration of C function 'int signbit(double)'
_GL_MATH_CXX_REAL_FLOATING_DECL_2 (signbit)
....

Additional info:
* package version(s) octave 3.8.1-1, hdf5 1.8.13-1
* config and/or log files etc.


Steps to reproduce:
Inside octave type: A=rand(2,2); save -hdf5 "A.h5" A
try to rebuild octave.
