s/bean/been Added on commit d1acb31 ("compile time: enable LTS", 2021-02-28).
Consider the current code:
AS_IF([test "x$enable_lts" = "xyes"], [
# ...
HAVE_CONTRIB_INSTALL="no",
Result of testing the value:
$ HAVE_CONTRIB_INSTALL="no",
$ printf '%s\n' "$HAVE_CONTRIB_INSTALL"
no,
$ test "x$HAVE_CONTRIB_INSTALL" = "xno" &&
echo equal || echo 'not equal'
not equal
This means that whenever HAVE_LTS is enabled, HAVE_CONTRIB_INSTALL is
always considered enabled when testing against "no".
But luckily, in the current code the latter variable is only tested
against "yes", so nothing should be affected:
$ git grep HAVE_CONTRIB_INSTALL |
grep -v -e '^configure:' -e '^configure.ac:'
Makefile:ifeq ($(HAVE_CONTRIB_INSTALL),yes)
config.mk.in:HAVE_CONTRIB_INSTALL=@HAVE_CONTRIB_INSTALL@

Added on commit d1acb31 ("compile time: enable LTS", 2021-02-28). Note: Do not print a preceding blank line because one is already printed right before the warning message, right after the items on "Features:". Example of the resulting warning message: $ autoconf && ./configure [...] configure: creating ./config.status config.status: creating config.mk config.status: creating config.sh Compile options: [...] prefix: /usr/local sysconfdir: ${prefix}/etc Spectre compiler patch: yes Features: [...] SELinux labeling support: user namespace: -DHAVE_USERNS X11 sandboxing support: -DHAVE_X11 ********************************************************* * Warning: Long-term support (LTS) was enabled! * * Most compile-time options have been rewritten! * ********************************************************* $
Instead of binding them together with conditionals in a single line, split shell commands into multiple lines to make them more readable. Note that for the macro arguments in question, the content inside [] quotes is output literally into ./configure, so the commands can be written as if they were in a shell script directly (save for any special characters/tokens in Autoconf). Misc: Relates to commit 2c64d1f ("use AX_CHECK_COMPILE_FLAG to check for spectre flags", 2019-06-21).
Misc: I missed this one on commit 221c101 ("configure*: Add missing quotes to arguments", 2021-06-03) / PR netblue30#4712.
