My Redhat 6.1 boxes have INFINITY defined in <bits/mathdef.h>  through
#includes from <math.h>

My Solaris 2.5.1's and 2.7's do not have such a definition
  even in usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2/include
        I stuck a define into globals.h 
        as a suffuciently large number
        to get the module to compile

NAN, INFINITY and some others are not consistent Linux to Linux, Unix to
Unix, Compiler to Compiler.
