Errors in the original -1 text and notes:

1. For libnotify, I had omitted to use a verbose build.  In manual testing,
 (not scripted) I seemed to have difficulty getting it to use my CFLAGS and
 eventually discovered that the documented way with meson is to use:

 CFLAGS=-fsomething LDFLAGS=-Wl,--linker-flag meson ...

 Possibly, I had merely failed to export the CFLAGS, but for this package
 I'm now using that appreoach, i.e.

 CFLAGS="$CFLAGS" meson --prefix=/usr ...

2. For flvstreamer, I typo'd the note number as [45], it should be [46].
 More seriously, the sed in that note was wrong, putting escaped double
 quotes around the CFLAGS causes the build to fail.  Corrected.
