Fabrice, All,

On 2022-10-30 18:56 +0100, Fabrice Fontaine spake thusly:
> Add libexecinfo optional dependency as upstream rejected the patch to
> add --with-execinfo=no

Indeed, they rejected it, but they suggested an alternate solution:
check for backtrace() and whether it requires -lexecinfo.

Something like:

    AC_SEARCH_LIBS(
        [backtrace],
        [execinfo],
        ,
        [AC_MSG_ERROR([backtrace() not found and no library provides it; maybe install libexecinfo])]
    )

Regards,
Yann E. MORIN.

Agreed, but for now, Fabrice's patch was good enough, so I applied
as-is. It will certainly be nice if Fabrice has the chance to work on a
better solution using AC_SEARCH_LIBS().
