Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
beep could not be built reproducibly.
This is because of obscure differences in backslash escaping between
the Bash and Dash shells in GNU Makefiles in/around:
set -e; IFS=""; while read line; do \
echo " \"$${line}\\\\n\"" >> $@; \
done < $<
This appears to produce "\n" with /bin/dash as /bin/sh or "\\n" with /
bin/bash. A patch is attached that replaces the echo line with a call
to printf which, in my experience, is not as fickle as echo and seems
more suited to this interpolation/template-type string maniplation.
