Seeing that both solenv/gbuild/platform/com_{GCC_defs,MSC_class}.mk 
already drop SOLARINC's -I. from gb_LinkTarget_INCLUDE, it is probably 
rather the latter -I$(dir $(3)) that can be dropped from 
gb_CObject__command_pattern in 
solenv/gbuild/platform/com_{GCC,MSC}_class.mk once you're done.

(And -I. dropped from SOLARINC in configure.ac as an orthogonal clean 
up?  Would need auditing what other places using SOLARINC (besides those 
gb_LinkTarget_INCLUDE that drop it anyway) might need it for.)
