Short version: thanks for the report, but I don't think that this is
correct.

First of all, FLTK_ABI_VERSION is deprecated but still defined in
FL/Enumerations.H. It should always be equal to FL_ABI_VERSION which you
should use since 1.3.4/1.3.5 and later.

The posted abi-version.h file is correct and intentional if you don't
specify an ABI version with configure. Again, there is code in
FL/Enumerations.H that defines FL_API_VERSION, FL_ABI_VERSION, and
FLTK_ABI_VERSION for backwards compatibility.

Note: do not include FL/abi-version.h directly in your code. You must
include FL/Fl.H which will include FL/Enumerations.H and FL/abi-version.h
indirectly. This is documented here:
https://www.fltk.org/doc-1.3/basics.html#basics_writing

Please see also README.abi-version.txt and attached small demo program
abi-version.cxx.

// compile with `fltk-config --compile abi-version.cxx'

#include <stdio.h>
#include <FL/Fl.H>

int main(int argc, char **argv) {
  printf("FL_API_VERSION   = %d\n", FL_API_VERSION);
  printf("FL_ABI_VERSION   = %d\n", FL_ABI_VERSION);
  printf("FLTK_ABI_VERSION = %d\n", FLTK_ABI_VERSION);
  return 0;
