in paragraph 3. I do remember I was not happy being forced to use 2 bits for holding a boolean. I've attached an example testcase for binary compatibility tests in the format used by the GCC testsuite.

Comment 16 Paolo Carlini 2013-07-05 22:36:27 UTC Janis, any idea what happened of this? http://www.cplusplus.com/forum/beginner/140745/ Request was from Debbugs Internal Request to [email protected] (Mon, 12 May 2008 09:41:22 GMT) Full text and rfc822 format available. This declaration gives only a signed 9-bit type, independent of the ABI.

AFAICT, G++ 4.0 is following the ABI. Matos Prev by Date: parsing configuration file Next by Date: Re: Can I stop linking the same library twice?

Since +128 is not representable in 9 signed bits, it wraps to -128. Please try the request again. GCC defines it to have one value bit with the other bits being padding bits and undefined behavior if you access a _Bool representation with any of the padding bits having For some versions of the compiler that comparison fails when done against the bitfield itself but not when compared against a char or int variable into which the bitfield has been

Does it mean that the programmer is about to loose, with this incoming compiler, the freedom of deciding the precise bit allocation of his fields? The anonymous bit field :0 causes the following bit field to be allocated into a distinct int.
