(with some delay)
succeeded in compiling on my old machine(s) with XP.
to run Pd it was necessary to copy libgcc_s_dw2.dll and pthreadGC-3.dll
from Mingw/bin
to pd/bin.
also VC90.CRT was needed; downloading vcredist_86.exe and installing
solved that.
i copied the externals from my W10 machine (bsaylor, comport, iemguts,
zexy);
so far so good.
thnx for the help(s).
