That does not make a difference.

Only after adding -D_GNU_SOURCE (for example in config.mk) __USE_GNU is 
defined via features.h and O_CLOEXEC is defined.

Adding _GNU_SOURCE results in another problem though:
cc  -Os -march=i486 -mtune=pentium -pipe -fomit-frame-pointer -Wall 
-Wextra -std=c99 -D_BSD_SOURCE -D_XOPEN_SOURCE=700 -D_GNU_SOURCE -DINET
