400 # In Cygwin, finds are very costly, both because of expensive forks and because
401 # of bad file system caching. Find is used extensively in $(shell) commands to
402 # find source files. This makes rerunning make with no or few changes rather
403 # expensive. To speed this up, these two macros are used to cache the results
404 # of simple find commands for reuse.
405 #
406 # Runs a find and stores both the directories where it was run and the results.
407 # This macro can be called multiple times to add to the cache. Only finds files
408 # with no filters.
