Hi Paul, With cc on HP-UX 11.31, test-stdint.c fails to compile:
cc -DHAVE_CONFIG_H -I. -I.. -DGNULIB_STRICT_CHECKING=1 -DIN_GNULIB_TESTS=1 -I. -I. -I.. -I./.. -I../gllib -I./../gllib -g -c -o test-stdint.o test-stdint.c cc: "test-stdint.c", line 414: error 1511: Bit-field size must be a constant. cc: "test-stdint.c", line 414: error 1613: Zero-sized struct. cc: "test-stdint.c", line 414: warning 504: The sizeof operator applied to a zero-sized object. cc: "test-stdint.c", line 416: error 1511: Bit-field size must be a constant. cc: "test-stdint.c", line 416: error 1613: Zero-sized struct. cc: "test-stdint.c", line 416: warning 504: The sizeof operator applied to a zero-sized object. cc: "test-stdint.c", line 419: error 1511: Bit-field size must be a constant. cc: "test-stdint.c", line 419: error 1613: Zero-sized struct. cc: "test-stdint.c", line 419: warning 504: The sizeof operator applied to a zero-sized object. *** Error exit code 1 The problematic line is: verify_width (WCHAR_WIDTH, WCHAR_MIN, WCHAR_MAX); In order to understand which of the three macros introduces the problem, I added three lines: int aa = WCHAR_WIDTH; int ab = WCHAR_MIN; int ac = WCHAR_MAX; The initializations of 'ab' and 'ac' were OK, but the first line gives an error: cc: "test-stdint.c", line 26: error 1521: Incorrect initialization. Since WCHAR_WIDTH expands to a sequence of ca. 12890 characters, apparently coming from gllib/stdint.h:# define WCHAR_WIDTH _GL_INTEGER_WIDTH (WCHAR_MIN, WCHAR_MAX) I would suggest to simplify _GL_INTEGER_WIDTH by assuming that its value MUST be one of 8, 16, 32, 64, 128. Gnulib does not attempt portability to machines with 36-bit words or 3-bit integer types. The same error appears also at verify_width (WINT_WIDTH, WINT_MIN, WINT_MAX); and verify_width (SIG_ATOMIC_WIDTH, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX); Bruno
