mlnlffigen generates a MLNLFFI binding from a collection of .c
files. It is based on the CKitLibrary, which is primarily designed
to handle standardized C and thus does not understand many (any?)
compiler extensions; however, it attempts to recover from errors when
seeing unrecognized definitions.
In order to work around common gcc extensions, it may be useful to add
-cppopt options to the command line; for example
-cppopt '-Dextension' may be occasionally useful. Fortunately,
most portable libraries largely avoid the use of these types of
extensions in header files.
mlnlffigen will normally not generate bindings for #included
files; see -match and -allSU if this is desirable.
