Personal tools Log in. C99 introduced several new features, many of which had already been implemented as extensions in several compilers: Here’s an example of a case where it’s useful: The latest defect report summary for C11 is available at n Has C99 support equal to that of GCC.
Category LanguageCategory Resources. It incorporates TCs Technical Corrigenda and does not introduce new language features.
Since ratification of the C standard, the standards working group prepared technical reports specifying improved support for embedded processing, additional character data types Unicode supportand library functions with improved bounds checking.

Destructor 6, 3 35 An example of this willingness to live with what the machine does can be seen in the rules that govern the widening of char objects for use in expressions: Normative Amendment 1 created a new standard for C inbut only to correct some details of the standard and to add more extensive support for international character sets.

The … overall goal was to develop a clear, consistent, and unambiguous Standard for [C] which codifies the common, existing definition of C and which promotes the portability of user programs… The original X3J11 charter clearly mandated codifying common existing practice, and the C89 Committee held fast to precedent wherever that was clear and unambiguous.
Pre-C89 implementations exhibit at least four different modelslisted here in order of increasing restrictiveness:. It is just about practice and experience.
I’ve rationalle over a couple of other places I thought might mention it, but found nothing. Before C99, compilers could round intermediate results inconsistently, especially when using x87 rxtionale hardware, leading to compiler-specific behaviour;  such inconsistencies are not permitted in compilers conforming to C99 annex F.

So, even if there was someone begging or campaigning for such a feature which there probably wasn’tit probably went down in the priority order. In my early daysa good C programmer was someone who knew what assembler the compiler generated.
