-Subject: [PATCH] libCom: detect support for backtrace() with __has_include.
-
-This is necessary in order to build epics-base with musl libc, for
-example, and any other C libraries which don't include this
-functionality. In order to not regress builds with older compilers, we
-still support the uclibc check. Furthermore, it has been checked that
-uclibc-ng (the maintained version of uclibc) doesn't install the
-<execinfo.h> header when the functionality is disabled [1] [2].
-
-To avoid repetition, we don't define HAS_EXECINFO to 0 when it is not
-available.
