Subject: Compiling Ruby Inline C code - resolving errors

I am trying to get this Ruby inline C code http://pastie.org/2825882 to
work. The code works in vanilla C, but here I get errors and warnings.
What causes this error?

./backtrack_inline.rb:67: error: lvalue required as unary '&' operand

Also, why do I get the following error?

./backtrack_inline.rb:73: error: too few arguments to function
'backtrack'

Inspecting the resulting C code ( http://pastie.org/2826036) I fail to
see anything wrong with the arguments. But I do also get the following
warnings:

./backtrack_inline.rb:73: warning: passing argument 1 of 'backtrack'
makes integer from pointer without a cast
./backtrack_inline.rb:73: warning: passing argument 2 of 'backtrack'
makes integer from pointer without a cast
./backtrack_inline.rb:73: warning: passing argument 3 of 'backtrack'
makes integer from pointer without a cast


Cheers,


Martin
