Notes for blitz++ - reproducible builds result

Version annotated: 1:0.10-3.2
Identified issues:
Identifier: records_build_flags
Description Records $CFLAGS, which vary intentionally due to the «-fdebug-prefix-map=${BUILDPATH}=.»,
«-ffile-prefix-map=${BUILDPATH}=.» or «-fmacro-prefix-map=${BUILDPATH}=.» flags.
.
We have a patch pending to GCC to fix this issue centrally:
.
https://gcc.gnu.org/ml/gcc-patches/2016-11/msg00182.html
.
Though the patch is currently unlikely to be merged. If/when this
is accepted, this issue should be fixed for all packages and you
should not need to fix it specifically in your package.
.
There is also a work-in-progress patch to dpkg that could address this issue:

Identifier: random_id_in_pdf_generated_by_dblatex
URL http://tug.org/pipermail/tex-live/2017-June/040398.html
Description eg.
/ID [<1ebdbec86dcab3e39cf225470b799ae8> <1ebdbec86dcab3e39cf225470b799ae8>]
.
Not caused by build path nor by the minute used to build at least.
Intermediate "--tempdir=docbuild" has no differences.
.
ID is varying because texlive generates it based on the build path, see also
pdf_id_varying_due_to_build_path issue.
