A quick question about -no-canonical-prefixes... By default, gcc calls realpath() on prefixes generated relative to argv[0] in the gcc driver. If gcc is held as a "symlink farm" the realpath() makes it fail (absent a lot of messy -B, -L, -isytem and so on). It complains about not finding cc1 or cc1plus in libexec.
-no-canonical-prefixes turns off realpath() to make gcc work cleanly when stored this way. Does anyone know a reason why -no-canonical-prefixes could not become the gcc default? Are there gcc configurations that must have the realpath()? The flag is benign on normally laid out gcc installations. If it did become the default case, would adding a symmetrical -canonical-prefixes to turn realpath() back on be worthwhile?
