It turns out that the values of DBL_MAX and DBL_MIN are one digit too short in /usr/include/float.h: this is a problem since DBL_MAX is rounded to the next highest digit and is therefore larger than the maximum representable double. The float.h generated by fixincludes also has a wrong value for DBL_MAX. The correct values for the DBL_* macros are #define DBL_MANT_DIG 53 #define DBL_EPSILON 2.2204460492503131E-16 #define DBL_DIG 15 #define DBL_MIN_EXP (-1021) #define DBL_MIN 2.2250738585072014E-308 #define DBL_MIN_10_EXP (-307) #define DBL_MAX_EXP (+1024) #define DBL_MAX 1.7976931348623157E+308 #define DBL_MAX_10_EXP (+308) > >There is also a circular dependancy for protoize.o/unprotoize.o in the >Makefile.

I think that the makefile will work without modification if you have GNU make installed. Chris Flatters cflatter@nrao.edu
