gcc linking error

Sympton:
/usr/lib/gcc/i586-suse-linux/4.1.2/../../../../i586-suse-linux/bin/ld: errno: TLS definition in /lib/libc.so.6 section .tbss mismatches non-TLS reference in \
/tmp/ccox5xu2.o
/lib/libc.so.6: could not read symbols: Bad value

Diagnosis:
Link error

Analysis:
/usr/include/unistd.h includes features.h which is using errno.h

So errno.h should be included.

Solution:
(Final)
#include before #include

(Temporary)
gcc -include /usr/include/errno.h code.c
