1.) __alignof__ is __builtin__alignof on sgi
2.) in fclang.h the { .stats = ... } (initializes a union) isn't understood by 
the compiler. Solution (not nice): reorder union definition of _FcChar to
union {
	struct {
	    int	    	leafidx_offset;
	    int	      	numbers_offset;
	} stat;
	struct {
	    FcCharLeaf  **leaves;
	    FcChar16    *numbers;
	} dyn;

    } u;
and ommit ".stats = "
3.) -lgen option while linking libfontconfig.la is neccessary (because basename
() is used)

sorry for this very short bug report
