Hi,

unfortunately GNAT Community 2019 ist no longer able to compile code of old Ada Versions:

$ gnatmake main.adb -gnat05
gcc -c -gnat05 main.adb
gnat1: invalid switch: -gnat05
gnatmake: "main.adb" compilation error

$ gnatmake main.adb -gnat2005
gcc -c -gnat2005 main.adb
gnat1: invalid switch: -gnat2005
gnatmake: "main.adb" compilation error

The same happens for -gnat95 and -gnat83

Only -gnat12 and -gnat2012 work:
$ gnatmake main.adb -gnat12
gcc -c -gnat12 main.adb
gnatbind -x main.ali
gnatlink main.ali

$ gnatmake main.adb -gnat2012
gcc -c -gnat2012 main.adb
gnatbind -x main.ali
gnatlink main.ali

Also the pragma Ada_2005 does not work:

gnatmake main.adb
gcc -c main.adb
main.adb:1:01: warning: pragma "Ada_2005" ignored
gnatbind -x main.ali
gnatlink main.ali

Sincerely
Charly
