Description Daniel Macks 2009-11-15 21:52:15 UTC 
I couldn't find a bug for tracking this known issue in liboil/liboiltypes.h:

>/**
> * NULL:
> *
> * FIXME: gtk-doc is broken and doesn't know how to ignore this.
> */
>#ifndef NULL
>#define NULL ((void *)0)
>#endif

but it's causing a mess with the gtk-doc I build for many other packages.

Is there any platform that doesn't have a NULL available somewhere in the system headers? Could:

Good way: have autoconf find that .h and #include it here (using autoconf template or something else like liboil-stdint.h does).

Hack way: #include lots of .h that are known to supply it on various platforms (possibly protected with AC_CHECK_HEADERS pragmas).

Looks like stddef.h is the standard file to #include to get the NULL token.
