minor fixes to improve flex compatability with g++ 3.0

[goon]

hi,

i did manage to cajole g++3.0 and flex 2.5.4a into talking
nicely with one another. differences follow.

one question remains. i would like to use something along
the lines of yy_scan_bytes() but as far as i can tell, there
is no c++ analog. am i missing something here?

thanks
erik
