* man/ffi_call.3: Fix #include in examples.
* doc/libffi.texi: Add dircategory.
2009-12-25 Frank Everdij <f.p.x.everdij@tudelft.nl>
* include/ffi.h.in: Placed '__GNUC__' ifdef around
'__attribute__((aligned(8)))' in ffi_closure, fixes compile for
IRIX MIPSPro c99.
* include/ffi_common.h: Added '__sgi' define to non
'__attribute__((__mode__()))' integer typedefs.
* src/mips/ffi.c (ffi_call, ffi_closure_mips_inner_O32,
ffi_closure_mips_inner_N32): Added 'defined(_MIPSEB)' to BE check.
(ffi_closure_mips_inner_O32, ffi_closure_mips_inner_N32): Added
FFI_LONGDOUBLE support and alignment(N32 only).
* src/mips/ffitarget.h: Corrected '#include <sgidefs.h>' for IRIX and
fixed non '__attribute__((__mode__()))' integer typedefs.
* src/mips/n32.S: Put '#ifdef linux' around '.abicalls' and '.eh_frame'
since they are Linux/GNU Assembler specific.

* configure.ac, Makefile.am, src/avr32/ffi.c,
src/avr32/ffitarget.h,
