# Slackware build script for csh
# Written by B. Watson (urchlay@slackware.uk)
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# 20230919 bkw:
# - update for v20230828_1 (sync with Debian sid).
# - remove old no-longer-needed bufsiz.diff and glibc-2.32-sys_siglist.diff.
# - add timespec.diff to work around breakage in csh's time builtin.
# - add remove_publib_dep.diff to avoid an external publib dependency.
# - update csh.login a bit (new csh has a different default $prompt).
# - mention bad profile scripts in README_Slackware.txt.
# - fix the man page slightly.
# 20220409 bkw: BUILD=2
# - fix doinst.sh: only create bin/csh symlink if bin exists, which
# fixes installing the package with 'installpkg -root /some/path'.
# 20210827 bkw:
# - update to latest debian patch (6), add deb version to VERSION.
# - add -current fix for recent glibc.
# 20170621 bkw:
# - update to latest debian patch (-2.2, needed for -current).
# - quit compiling with -Werror (also needed for -current).
# - BUILD=2.

# 20230919 bkw: My own patch. Provides an implementations of
# xrealloc(), and replaces xfree() with free(), so we don't have
# publib as a dependency.
patch -p1 < $CWD/remove_publib_dep.diff
# 20230919 bkw: My own patch. Fixes the mess caused by debian's
# bsd_time.patch. We need the patch, but it introduces a bug where a
# 'struct timeval' pointer is treated as a 'struct timespec' pointer,
# leading to a broken time builtin.
# This isn't *just* here to fix a compiler warning! Without this
# patch, we get:
# % time sleep 2.3
# 0.0u 0.0s 0:02.99 0.0% 0+0k 0+0io 0pf+0w
# ...it thinks a 2.3 second sleep took 2.99 sec. Sometimes this
# will print as 0:02:00 instead (also wrong). With the patch:
# % time sleep 2.3
# 0.0u 0.0s 0:02.30 0.0% 0+0k 0+0io 0pf+0w
# This wasn't an issue in the previous (20110502_6) version.
