Update.

Use ## directly instead of __CONCAT so that the suffix string is not expanded as a macro. * sysdeps/wordsize-64/stdint.h (INT8_C, INT16_C, INT32_C, INT64_C, UINT8_C, UINT16_C, UINT32_C, UINT64_C): Likewise.

+2.28. Why is extracting files via tar so slow?
+
+{AJ} Extracting of tar archives might be quite slow since tar has to look up
+userid and groupids and doesn't cache negative results. If you have nis or
+nisplus in your /etc/nsswitch.conf for the passwd and/or group database,
+each file extractions needs a network connection. There are two possible
+solutions:
+
+- do you really need NIS/NIS+ (some Linux distributions add by default
+ nis/nisplus even if it's not needed)? If not, just remove the entries.
+
+- if you need NIS/NIS+, use the Name Service Cache Daemon nscd that comes
+ with glibc 2.1.
