Dylan, 

The thinplatespline.cpp file attempts to include either float.h or
values.h if they are available (as determined by configure). 
Does your gdal/port/cpl_config.h include #defines for 
HAVE_FLOAT_H and/or HAVE_VALUES_H? 

I have altered thinplatespline.cpp to include the following
optional definition after the attempt to include float.h and values.h:

#ifndef FLT_MAX
#  define FLT_MAX 1e+37
#  define FLT_MIN 1e-37
#endif

You can apply the same change to your local version. 

Best regards,
