I have a library with full source code that I will recompile. However, In 
the example I provided I have written a small DLL that I'm compiling. 
Compiling it thsi way works:

gnatmake -c api
gnatbind -n api
gnatdll -d api.dll api.ali

However, using GPS with the settings I provided does not work. Making the 
project gives the following output:

gnatmake -PI:\Temp\ADATest\AdaDLL\api.gpr -d
gnatbind -n -o b~api.adb -Lapi -a api.ali
gcc -c b~api.adb

building dynamic library for project api

to `adafinal'
collect2: ld returned 1 exit status
gnatmake: gcc execution error

process exited with status 4

I have problems seeing whats wrong. I have treid different settings for 
Library_Auto_Init, but with the same result.
