-- Macro: AC_TYPE_UINT8_T
If `stdint.h' or `inttypes.h' defines the type `uint8_t', define
`HAVE_UINT8_T'. Otherwise, define `uint8_t' to an unsigned
integer type that is exactly 8 bits wide, if such a type exists.
but for some reason HAVE_UINT8_T is not defined! (Today's CVS)
% cat configure.ac
AC_INIT([autotype],[1.0])
AC_CONFIG_HEADERS([config.h])
AC_TYPE_UINT8_T
AC_OUTPUT
% autoreconf
% ./configure
...
checking for uint8_t... yes
...
config.status: creating config.h
% grep UINT config.h
/* #undef _UINT8_T */
The attached patch fixes this..
(Also removes what appear to be spurious #( )
Also, AC_TYPE_SIZE_T does not claim to define HAVE_SIZE_T, (as it
uses _AC_CHECK_TYPE_OLD) - would defining HAVE_SIZE_T be considered
an improvement?
Cheers,
Patrick
