Under Linux I do: include <math.h> ... reciprocal=NAN;
When I try to compile this under cygwin, gcc complains that NAN is undefined.
Under cygwin, "man nan", tells me about a function named nan(), also using math.h.
When I try to use it, gcc complains about an implicit declaration of nan().
I am attaching relevant portions of the Makefile I am using to the end of this
message.
Help would be appreciated.
