* common/w32-reg.c (read_w32_reg_string): Add arg r_hklm_fallback and change all callers. (show_configs): Indicate whether the HKLM fallback was used. * tools/gpgconf.c (show_other_registry_entries): Fix the Outlook Addin Registry key. Indicate whether the HKLM fallback was used. -- Note that this is backport from 2.2. The new support there for REG_DWORD needs to be implemented in libgpg-error, though.
