Move AM_V_GEN to recipe start
This is especially needed when building Emacs, as it uses
‘AM_V_GEN=@$(info GEN $@)', which means the GEN line is output by
GNU make just before the recipe runs, regardless of where AM_V_GEN
appears in the recipe. And it’s also good practice even if the
default Automake ‘AM_V_GEN=@echo GEN $@;’ is used, as it’s better
to output the GEN line consistently at the start of every recipe,
even if this precedes a preparatory command that almost always
works silently.

Depend on ialloc not idx.

backupfile: fix numbered backups for XXX/
This fixes Bug#52410 reported by Vincent Vermilya.
* lib/backupfile.c (check_extension): Return a bool indicating
whether the original extension was OK. Caller changed.
(numbered_backup): Require that FILELEN does not count
trailing slashes after a non-slash, and don’t require
that *BUF be null-terminated. Caller changed.
This fixes a bug where the numbered backup file name for X/ was
incorrectly computed because the trailing slash messed up the code
looking for X.~1~, X.~2~, etc., and this caused numbered_backup
to loop forever. Also, check that check_extension doesn’t
truncate a file name leading to a different infloop.

regex: pacify Coverity clean_state_log_if_needed
Problem reported by Robbie Harwood in:

Add a DEBUG_ASSERT; this both pacifies Coverity and

intprops: streamline and get ready for Clang 14
* lib/intprops.h (_GL_HAS_BUILTIN_ADD_OVERFLOW):
Rely on __has_builtin first, since GCC didn’t introduce it until

Look at __EDG__ rather than __ICC, since icc defines __EDG__ too.

as a bug fix is scheduled for Clang 14.
(_GL_HAS_BUILTIN_OVERFLOW_P): Do not bother to special-case
__clang__, since __has_builtin should do the right thing anyway.
