/*
  Check if FL_ABI_VERSION is out of allowed range; redefine if necessary.
 
  This is done to prevent users from defining an illegal ABI version.
 
  Rule: FL_MAJOR_VERSION * 10000 + FL_MINOR_VERSION * 100
          <= FL_ABI_VERSION <= FL_API_VERSION + 1.
 
  Since FLTK 1.4.2+ (Git commits after release 1.4.2) FL_ABI_VERSION is
  allowed to be one higher than FL_API_VERSION so ABI changes in Git
  targeted at the *next* release (e.g. 1.4.3) can be used.
 
  Example: Commits after release FLTK 1.4.2 (before release 1.4.3):
 
    10400 <= FL_ABI_VERSION <= 10403
 
  Note: configure + CMake can be used to define FL_ABI_VERSION, but they
  do not check validity. This is done here.
