See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html and the surrounding thread. * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar rather than fgets, and retry after EINTR. Otherwise, 'emacs --batch -f byte-compile-file' fails on OpenBSD if an inactivity timer goes off. * s/openbsd.h (BROKEN_SIGIO): Define. * unexelf.c (unexec) [__OpenBSD__]: Don't update the .mdebug section of the Alpha COFF symbol table.
This directory contains C header files containing operating-system-specific definitions. Each file describes a particular operating system. The emacs configuration script edits ../config.h to include the appropriate one of these files, and then each emacs source file includes config.h. template.h is a generic template for system descriptions; it describes the parameters a system file can specify.
