[nhc-bugs] Build Error under nhc98

[Brent A. Fulgham]

When using the original nhc98 binaries I built from the
included C sources, I got a build error while building
...../prelude/Binary/PutBits.gc

Greencard complained about 'foreign' being an undefined:

/home/bfulgham/nhc98-1.04/script/nhc98 -cpp -c +CTS -part -redefine -CTS   -o /home/bfulgham/nhc98-1.04/targets/ix86-Linux/obj/prelude/Binary/PutBits.o PutBits.gc
No C type decl for variable foreign in DIS:
Apply (Constructor "BH") [Apply (Declare "BinHandle" (Var "bh")) [Apply (Var "foreign") [Exp "finaliseBH",Var "bh"]]]
greencard-nhc98 failed on ./PutBits.gc
make: *** [/home/bfulgham/nhc98-1.04/targets/ix86-Linux/obj/prelude/Binary/PutBits.o] Error 1

Comparing this directory with one in which "foreign" style
functions compiled successfully, I found that the IO directory
was omitted.  This patch allows the build to complete successfully,
though I don't know if it is the best possible fix.

Thanks,

-Brent
