# define ENABLE_ASH_INTERNAL_GLOB 1
#endif
#if !ENABLE_ASH_INTERNAL_GLOB && defined(__UCLIBC__)
# error uClibc glob() is buggy, use ASH_INTERNAL_GLOB.
# error The bug is: for "$PWD"/<pattern> ash will escape e.g. dashes in "$PWD"
# error with backslash, even ones which do not need to be: "/a-b" -> "/a\-b"
# error glob() should unbackslash them and match. uClibc does not unbackslash,
# error fails to match dirname, subsequently not expanding <pattern> in it.
