And gnulib rejects Solaris 10 and glibc's versions as buggy as well: http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00118.html > > ISO/IEC 9899:TC2 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf) > has the following to say: > > 7.18.4.1 Macros for minimum-width integer constants > > The macro INTN_C(value) shall expand to an integer constant expression > corresponding to the type int_leastN_t. The problem is that there is no integer constant expression for unsigned char; instead, you get an integer constant expression for the type that unsigned char promotes to. Therefore, UINT8_C should give an int, not unsigned int. This snippet from gnulib is valid C code, but fails if you use the wrong type specifier: /* Detect bugs in glibc 2.4 and Solaris 10 stdint.h, among others. */ int check_UINT8_C: (-1 < UINT8_C (0)) == (-1 < (uint_least8_t) 0) ? 1 : -1; int check_UINT16_C: (-1 < UINT16_C (0)) == (-1 < (uint_least16_t) 0) ? 1 : -1; - -- Life is short - so eat dessert first!
