265501: Merge 32 and 64 bit versions of prcpucfg.h on Solaris Flag _LP64 is not defined by any compiler (gcc and Forte 9) on AMD64 machine. Using the following logic: if __sparc or sparc if __sparcv9 : 64 bit sparc else : 32 bit sparc else if __x86_64 : 64 bit AMD elseif i386 or __i386: 32 bit x86 else : unknown processor
