7Subject: [PATCH] build: Move dnl comments out of AC_CHECK_FUNCS
8
9Due to a bug, autoheader (2.69) will treat M4 dnl comments in a quoted
10argument of AC_CHECK_FUNCS as function tokens and generate a lot of
11redundant and useless HAVE_* macros in config.h.in.
12(Examples: HAVE_DNL, HAVE_AVAILABLE_, HAVE_BY)
13
14It seems to be this commit dbb4e94dc7bacbcfd4acef4f085ef752fe1aa03f of
15mine that revealed this autoheader bug, and the affected config.h.in
16had been shipped within flex-2.6.4 release tarball.
17
18I have reported the autoheader bug here:
19<https://lists.gnu.org/archive/html/bug-autoconf/2018-02/msg00005.html>
20
21As a workaround, let's move comments out of AC_CHECK_FUNCS.
