Bug ID: 60652 Summary: System.OS_Constants CRTSCTS Product: gcc Version: 4.8.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada Assignee: unassigned at gcc dot gnu.org Reporter: robert.samuelsson at sscspace dot com The value of CRTSCTS in adainclude/s-oscons.ads is different to the value i have in /usr/include/bits/termios.h on my Linux system. adainclude/s-oscons.ads CRTSCTS : constant := 4294967295; -- Output hw flow control Hex: FFFF FFFF Dec: 4294967295 Oct: 37777777777 Bin: 11111111 11111111 11111111 11111111 (looks more like a mask than a flag) bits/termios.h #define CRTSCTS 020000000000 /* flow control */ Hex: 8000 0000 Dec: 2147483648 Oct: 20000000000 Bin: 10000000 00000000 00000000 00000000 (ah, a bit-flag as expected) So I suspect there may be a problem with the autogenerator and octal numbers. I do not know if any other generated constants have similar problems.
