There were # a few restrictions though: The "redirected" path had to start with a slash, # and it had to exist (see ModifyWord_Realpath). # # This unintended behavior was caused by cached_realpath using a GNode for # keeping the cache, just like the GNode for global variables. .MAKEFLAGS: -dd does-not-exist.c= /dev/null # expect+1: does-not-exist.c .info ${does-not-exist.c:L:tA} # expect+1: does-not-exist.c .info ${does-not-exist.c:L:tA} # The output of the following line is modified by the global _SED_CMDS in # unit-tests/Makefile.
