有关GNU C编译器的信息......？ [英] Info about the GNU C Compiler...?

我知道它是一个免费的编译器。但它遵循任何标准吗？如果是这样
这个标准是什么？ （Ansi，Ecma等？）
I know it is a free compiler. But does it follow any standard? If so
which standard is it? (Ansi, Ecma, etc?)

您在发布之前是否只看过GCC文档？
Google GCC - http://gcc.gnu.org/onlinedocs/ - >
* GCC 4.1.2手册 - >
＃1 GCC支持的编程语言
＃2 GCC支持的语言标准

Did you have a single look at GCC documentation before posting ?
Google GCC -http://gcc.gnu.org/onlinedocs/ ->

gcc / glibc实现非常符合1989 ANSI C
标准，后来更新ISO作为ISO / IEC 9899：1990采用。
它并不声称符合1999年以后的ISO标准，但在
事实上支持最多那个标准的变化是C.它达到了这个不是
那里几年前的一致性水平，并且在可预见的未来没有显示出接近C99的迹象。

The gcc/glibc implementation conforms extremely well to the 1989 ANSI C
Standard, which was later adopted by ISO as ISO/IEC 9899:1990.
It does not claim to conform to the later 1999 ISO Standard, but does in
fact support most of that Standard''s changes to C. It reached this "not
quite there" conformance level some years ago, and shows no signs of
approaching C99 any more closely for the foreseeable future.

[OT]
当语言扩展允许时，gcc仍然断言__STDC__
允许（即，编译器没有在严格的
一致性模式下调用）？他们曾经这样做，并且可以原谅它说不符合ANSI / ISO标准的编译器b $ b可以随意做任何他们想做的事，包括
断言
的宏可能会导致程序认为它是由
编译的ANSI / ISO标准编译器。

[OT]
Does gcc still assert __STDC__ when language extensions have been
allowed (i.e., when the compiler was not invoked in strict
conformance mode) ? They used to do that, and would excuse it
by saying "Compilers which do not adhere to the ANSI/ISO standards
are free to do whatever they want, including asserting macros that
might lead a program to believe that it ws being compiled by
an ANSI/ISO standard compiler."
