I think for your purpose it suffices to add something like
this to pdftosrc.cc:main():

#ifdef POPPLER
    fprintf(sdterr, "warning: this version of pdftosrc doesn't support object stream (use pdftosrc from TeX Live if you need it)");
#endif

so that if someone happens to use pdftosrc, he/she will be
warned.
