File libcurl-ocloexec.patch of Package curl.27750
Open library file descriptors with O_CLOEXEC This patch is non-portable, it needs linux 2.6.23 and glibc 2.7 or later, different combinations (old linux, new glibc and vice-versa) will result in a crash. To make it portable you have to test O_CLOEXEC support at *runtime* compile time is not enough.
