如何获取POSIX strerror_r而不是GNU版本?
我正在使用glibc 2.7版(基于其中的内容)在Ubuntu 8.04上使用g ++进行编译.

在上面的手册页中,它说:
glibc的功能测试宏要求(参见feature_test_macros(7)):
The XSI-compliant version of strerror_r() is provided if:
(_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600) && ! _GNU_SOURCE
Otherwise, the GNU-specific version is provided.

If no feature test macros are explicitly defined, then the following feature
test macros are defined by default: _BSD_SOURCE, _SVID_SOURCE, _POSIX_SOURCE,
and _POSIX_C_SOURCE=200809L (200112L in glibc versions before 2.10; 199506L in
glibc versions before 2.4; 199309L in glibc versions before 2.1).

所以我应该得到POSIX版本,但我得到的是GNU版本.
