+ regex: allow inclusion of <regex.h> before <limits.h>
+ Without this patch, portable programs had to include <limits.h> before
+ <regex.h> if they wanted a consistent value for RE_DUP_MAX.
+ I ran into this problem with a test version of GNU grep on Solaris 8.
+ * lib/regex.h: Include <limits.h> if _REGEX_INCLUDE_LIMITS_H.
+ This is done conditionally so that this change can be merged
+ back to glibc.
+ * m4/regex.m4 (gl_REGEX): Define _REGEX_INCLUDE_LIMITS_H if
+ using the included regex.
+
+ fts: depend on fdopendir
+ * modules/fts (Depends-on): Depend on fdopendir. This is needed
+ on Solaris 8, at least, since it lacks fdopendir. Evidently the
+ problem was introduced when fdopendir was split out.
