Right - We (The Embedded Sig) had decided to let the facts speak and not
to contact the FPC. I agreed to this approach, because it implemented
viable precedences and avoided lengthy and fruitless discussions, as I
had been confronted with before in FPC.

In case of openalpp it's only -lOpenThreads.

I can't comment on the situation of osgal and osgcal, because I haven't
seen Chris sources, yet. IIRC, at least one of these packages currently
to be found in CVS, still uses Producer and relies on OSG1's API.

- It's how things are supposed to work with pkg-config:

 From /usr/share/aclocal/pkg.m4:
AC_ARG_VAR([$1][_CFLAGS], [C compiler flags for $1, overriding pkg-config])dnl
AC_ARG_VAR([$1][_LIBS], [linker flags for $1, overriding pkg-config])dnl

- It's how things are supposed to work with autoconf in general:
configure CFLAGS=...
