GLib depends on various parts of a valid C99 toolchain, so it's time to
use C99 integer types wherever possible, instead of doing configure-time
discovery like it's 1997.
So:
gint8 → int8_t guint8 → uint8_t
gint16 → int16_t guint16 → uint16_t
gint32 → int32_t guint32 → uint32_t
gint64 → int64_t guint64 → uint64_t
gsize → size_t
gintptr → intptr_t guintptr → uintptr_t
There are some side effects on switching to C99:
- the G_*_MODIFIER macros do not really make any more sense, and should
be deprecated and replaced by an empty string
- the G_*_FORMAT macros are marked for use with both printf() and
scanf(), except that's not really true at all; C99 defines format
macros for print() and scanf() separately, and GLib should do the
same. The old macros should be deprecated, but if we want to be evil
about it, we could alias them with the PRINTF_FORMAT, as it's likely
their more dominant use
In general, there shouldn't be any ABI changes, unless the toolchain in
use is not conformant to C99.
