/usr/src/ark/BUILD/ooo-build/build/oog680-m7/sw/source/ui/uno/swdet2.cxx:91: internal compiler error: canonical types differ for identical types const char [5] and const sal_Char [5]

This is similar to bug 33886, may be just another test case for the same bug:

Difference from bug 33886: bug 33977 occurs even at -O0, 33866 needs -O2

Reduced test case

typedef char sal_Char;
const sal_Char sHTML[] = "HTML";
extern const char sHTML[];

	PR c++/33886
	* c-common.c (c_build_qualified_type): Moved to c-typeck.c.
	(complete_array_type): Set canonical type appropriately.
	* c-typeck.c (c_build_qualified_type): Moved from c-common.c. The
	C and C++ front ends now have different versions of this function,
	because the C++ version needs to maintain canonical types here.
