* configure.in (VERSION): Bump to 1.4.2. * NEWS: Describe 1.4.2's changes. * src/m4.c (reference_error): Preserve errno, since M4ERROR relies on this. * src/builtin.c (m4_esyscmd): Clear errno before calling popen. (m4_maketemp): Clear errno before calling mkstemp. * src/path.c (path_search): Don't let "free" trash errno when returning NULL. * src/output.c (insert_file): Don't assume errno has a valid value simply because fread returns zero. This fixes a portability bug reported by Marion Hakanson in <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>. Fixes PR pkg/27301. |
