When the application has requested the gnulib 'gethostname' module, it
means that the application wants to use a POSIX compatible gethostname()
function and not the original Windows gethostname().
Such an override logic does not apply for DATADIR. Asking for socket
functionality does not imply "I don't want to use the DATADIR macro",
and asking for the 'configmake' module does not imply "I want to hide
parts of the native Windows API". So, we cannot resolve the issue this way.
I can see two possible fixes:
a) Change the 'configmake' module to define MAKEVAR_DATADIR instead of
DATADIR.
b) Document that "configmake.h" should be included after all the
replacements of POSIX header files:
#include <alloca.h>
...
#include <wctype.h>
#include "configmake.h"
And in fact, b) is already implemented since 2008! The module description says:
Include:
/* Include only after all system include files. */
"configmake.h"
I'd suggest to add this recommendation also to doc/configmake.texi.
