From Jacek Holeczek:

Fix some bugs in the "Pythia-6" interface:
1. the "pyuppr" /PYUPPR/ common DOES NOT EXIST in Pythia-6 fortran code;
   all references to it (and to all variables that it "declares": NUP,
   KUP, NFUP, IFUP, PUP, Q2UP) are void.
2. the "pyssmt" /PYSSMT/ common IS TOO SHORT with respect to Pythia-6
   fortran code; the "pythia6_common_address.c" should define it as:
	int pyssmt[2*4*4+2*2*2+2*2*2+2*4+2*2+2*4*16+2*4*4+2*2*2+2*2*2];
   and the file "./pythia6/inc/TPythia6Calls.h" should declare it as:
	struct Pyssmt_t {
		double ZMIX[4][4];
		double UMIX[2][2];
		double VMIX[2][2];
		double SMZ[4];
		double SMW[2];
		double SFMIX[4][16];
		double ZMIXI[4][4];
		double UMIXI[2][2];
		double VMIXI[2][2];
	};
