Files generated from webservice and command line are different
David , I have following problem.
My changes for Delphi compiler are based on the file generated from webservice.
When I tried to generate same file (same options) with Python script I found difference (master branch).
Output (file glad/glad_gl.pas - from Python script,  file glad_gl.pas - from webservice).
Difference - **duplicated constant identifiers**.
Please, advice.
Regards.
Julian.
