* commit 'c0fbc5c086566d5d3c1d1ef26baa81a53d59fc08': (24 commits)
Use the right format string, "%zu", for size_t.
Repair more format strings.
Fix a bunch of format string errors reported by Larry.
Fix some HDfprintf compilation errors: use the right format strings ("zu", PRIuHSIZE), avoid casting some printf arguments, pass the right number of arguments.
Test the format string "ll" before "l", "L", and "q", like the ./configure script does. This ought to fix the compilation failure in test/dt_arith.c that Allen told me about:
Cast a non-void pointer to void pointer for "%p".
Use PRIu32 and "zu" formats. Delete some casts from `size_t`.
I'm taking a guess that this code intended to point the 2-digit wide hexadecimal octet values, not 2 character-wide pointers to the bytes. The %02p format, which is a GNU-ism, disagreed with GCC 8.3.0 and the option flags we use.
%08p is not portable, it's a GNU-ism. Use %8p, instead. Squashes a GCC error.
Add format string macros PRI[doxX]HID for hid_t and use PRIdHID.
Use HDva_copy() and introduce a bunch of compatbility format-string constants for uppercase hexadecimal strings, `PRIX...`. Should fix the VS2010 errors that Allen mentioned:
Always #define HDfprintf as fprintf in this header. I believe this will fix the Windows build error that Allen reported.
Provide an HDvasprintf implementation only if it isn't #defined. This should fix the mingw compilation issue that Allen reported.
Fix va_list usage in the vasprintf(3) implementation.
Promote format-string warnings to errors.
Use the portable `-eq` operator instead of the bash-ism `==`. Fixes the tests on NetBSD, where /bin/sh != bash.
Restore a literal percent sign ("%%") that I accidentally deleted.
Fix code that made GCC complain about a NULL or `unsigned char *` arguments for "%s".
Take pains to provide UINT64_MAX in all conditions.
Correct a couple of format strings.
