This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU Libtool configure 2.4.6, which was
generated by GNU Autoconf 2.69.  Invocation command line was

configure:2687: checking for GNU M4 that supports accurate traces
configure:2726: error: no acceptable m4 could be found in $PATH.
GNU M4 1.4.6 or later is required; 1.4.16 or newer is recommended.
GNU M4 1.4.15 uses a buggy replacement strstr on some systems.
Glibc 2.9 - 2.12 and GNU M4 1.4.11 - 1.4.15 have another strstr bug.
