Hello Maurício,

I did read that. It says I can use "#def" to insert
a C definition, but there are no examples of use, and I
could not find one.
#def inline int signof(int x) {return x<0?-1:x>0?1:0;}
foreign import ccall safe ""
signof :: CInt -> CInt
main = print (signof 33)
compilation:
hsc2hs tabi.hsc
ghc --make tabi.hs tabi_hsc.c
That use of "inline" doesn't have any effect since GHC 6.10, because
even when using -fvia-C we're not #including the header file in the
generated C code.
Also that note in the docs about not using #def in library code is
outdated: it should be safe to use #def in libraries now. I've fixed
the docs.
Cheers,
Simon
