[PD-dev] patch to ease the compilation of gem2pdp

hi.

i was having a hard time to compile gem2pdp (forgot to mention that in my last post) on linux

my g++ (3.3.5 (Debian 1:3.3.5-8)) refuses to cast (t_int*) to (int*) i therefore had to change the type of m_packet0 in gem2pdp.h to "int".

furthermore i find it very annoying that i have to set the path to my gem and pdp installation by hand in configure.ac since i prefer command-line flags i have added 3 of them (--with-gemdir=<gempath> --with-pdpdir=<pdppath> --with-pddir=<pdpath>) to the configure.ac, which allows me to overrule the hardcoded paths

attached is a patch against the CVS.

hope this works
