No, kst-fits doesn't check.  cfitsio does it itself.  I just double
checked by compiling a test program (which just opened a fits file or
two); on the first call to a cfitsio function when I have a binary
compiled against a different version of the resident cfitsio library
cfitsio errors out with the following text:

ERROR: Mismatch in the version of the fitsio.h include file used to build
the CFITSIO library, and the version included by the application program:
   Version used to build the CFITSIO library   = 3.100000
   Version included by the application program = 3.130000

FITSIO status = 104: could not open the named file

CCFits ran into this problem a while back.  I think most programs
haven't been hit because cfitsio is updated relatively rarely.  But I'm
not 100% positive.
