Gillian,

thinplatespline.c is supposed to be picking these up in either 
float.h or values.h based on:

#ifdef HAVE_FLOAT_H
#  include <float.h>
#elif defined(HAVE_VALUES_H)
#  include <values.h>
#endif

The logic to define HAVE_FLOAT_H or HAVE_VALUES_H was added
to the GDAL configure somewhat recently.  Note that a cvs update without
re-running configure will miss this.  Any change that is what you did? 

If despite all these there is still a case where FLT_MIN and FLT_MAX
are not defined feel free to commit such a change.   Just verify the problem
isn't that you didn't rerun configure.

Best regards,
