Error 698: "../../../dist/./include/nsIDOMNode.h", line 125 # Error limit reached; halting compilation. D GetOwnerDocument(nsIDOMDocument** aOwnerDocument) { return _to##GetOwnerDocument(aOwnerDocument); } \ ^^^^^^^^^^^^^^^^^^^^^ NEXT gmake[3]: *** [nsRDFElement.o] Error 2 Each line like that in the macro failed. This is visible on the HP-UX 10.20 tinderbox on the ports page (eggroll). nsRDFElement.cpp includes nsXULTreeElement.h and on: http://lxr.mozilla.org/seamonkey/source/rdf/content/src/nsXULTreeElement.h#43 it calls that macro, passing it mOuter-> and then compile go boom. cc'ing vidur since the macro was defined in DOM land. assigning to waterson since the calling of the macro is in RDF/XUL land.

I think the right thing to do is change: NS_IMETHOD GetNodeName(nsString& aNodeName) { return _to##GetNodeName(aNodeName); } \ to NS_IMETHOD GetNodeName(nsString &aNodeName) { return _to/**/GetNodeName(aNodeName); } \ and so forth. I think strict C says that ## can only be used to create a valid single token, the the latter form will at worst insert a harmless space when the preprocessor is done with it.

Vidur: I've regenerated the core DOM header files with the above patch for idlc. Did a full rebuild on Win32: it works fine. I've also spot-checked Mac and Linux, so it looks like this'll be okay. Give the word and I'll check in the patch to idlc and the re-generated DOM headers.

Actually, let me correct the above statement. I regenerated _all_ the DOM header files (all of mozilla/dom/public/idl).

Go for it, Chris.
