Actually the good folks at Linux have broken errno:

9l -o o.9660srv main.o 9660srv.o xfile.o iobuf.o data.o
/usr/bin/ld: errno: TLS definition in /lib/libc.so.6 section .tbss
mismatches non-TLS reference in main.o
/lib/libc.so.6: could not read symbols: Bad value
collect2: ld returned 1 exit status

The include of errno.h is a necessary appeasment.
