No, it's that he's using plain gcc to link rather than gnat tools.

This works for me (after including adainit(), adafinal() as a previous
poster suggested):

smaug.pushface.org[9]$ gnatmake -c paquete                         
gcc -c paquete.adb
smaug.pushface.org[10]$ gnatbind -n paquete.ali
smaug.pushface.org[11]$ gnatlink paquete.ali progC.o
smaug.pushface.org[12]$ ./paquete 
Hello
3 + 2 = 5
