- Update to glibc 2.37
* The getent tool now supports the --no-addrconfig option
* The dynamic linker no longer loads shared objects from the "tls"
subdirectories on the library search path or the subdirectory that
corresponds to the AT_PLATFORM system name, or employs the legacy AT_HWCAP
search mechanism, which was deprecated in version 2.33
- printf-grouping.patch: Account for grouping in printf width (BZ #30068)
- strftime-time64.patch: Use 64-bit time_t interfaces in strftime and
strptime (BZ #30053)

Subject: [PATCH] Use 64-bit time_t interfaces in strftime and strptime (bug
|
|
30053)
|
|
|
|
Both functions use time_t only internally, so the ABI is not affected.
