unistd

[JOLY Loic]

I do not know if this issue is still present in the current release of
flex, but in my version, the generated files are not standard C.

They indeed #include the non standard file unistd.h

I do not know what is the use of this file, since the generated code
seems to work perfectly if I remove this line.

So I would appreciate to know if this line could be removed from the
generated file.

Thanks,
