 Which old compilers? gcc-4.2?

 This suggests your compiler defaults to C89 mode, like gcc-4.2.

 > {{{

 directory
 > }}}

 H5public.h contains:

 {{{#!c
 #ifdef __cplusplus
 #include <cinttypes>
 #else
 #include <inttypes.h>
 #endif
 }}}

 So it requires `<cinttypes>` (from C++11) when in C++ mode and
 `<inttypes.h>` (from C99) when in C mode; any port including this file
 should use `configure.cxx_standard 2011` or `configure.c_standard 1999` as
 appropriate, and if it doesn't already add its own `-std` flags, add
 `configure.cxxflags-append -std=c++11` or `configure.cflags-append
 -std=gnu99` as appropriate.
