annotate libinterp/octave-value/ov-fcn-handle.cc @ 21022:ebc439187d29
avoid old-style cast warnings from HDF5 macros used in C++ sources
* oct-hdf5-types.h (octave_H5E_DEFAULT, octave_H5P_DEFAULT,
octave_H5S_ALL): New global variable declarations.
* coct-hdf5-types.c: New file.
* libinterp/corefcn/module.mk (COREFCN_SRC): Add it to the list.
* ls-hdf5.cc, oct-hdf5.h, ov-base-int.cc, ov-bool-mat.cc,
ov-bool-sparse.cc, ov-bool.cc, ov-cell.cc, ov-class.cc, ov-complex.cc,
ov-cx-mat.cc, ov-cx-sparse.cc, ov-fcn-handle.cc, ov-fcn-inline.cc,
ov-float.cc, ov-flt-complex.cc, ov-flt-cx-mat.cc, ov-flt-re-mat.cc,
ov-range.cc, ov-re-mat.cc, ov-re-sparse.cc, ov-scalar.cc,
ov-str-mat.cc, ov-struct.cc:
Use new variables in place of the corresponding HDF5 macros.
