I fully concur with Ludovic.
Btw, the file can also be examined online here:
http://anonscm.debian.org/gitweb/?p=collab-maint/pcsc-cyberjack.git;a=blob;f=m4/pcsc.m4
AFAIUI, Martin Preuss, the original author of that file, does no longer
work on it and Frank has taken over maintenance of the whole
pcsc-cyberjack package. Frank, is this correct?
In any case, I'd suggest to drop the file m4/pcsc.m4 package completely,
and replace it with pkg-config, because It seems that pcsc-lite does
provide a proper libpcsclite.pc file:
http://anonscm.debian.org/viewvc/pcsclite/trunk/PCSC/src/libpcsclite.pc.in?revision=2721&view=markup
pkg-config does work on all platforms that m4/pcsc.m4 implements (i.e.,
windows, macosx and linux), and is implemented technically much superior
way.
Cheers,
Reinhard.
