Actually it is possible to circumvent using gcc linker switches like 
--whole-archive. But admittedly, it is too complicated.

Why do you want to include everything? I guess that you do not use

    for Source_Files

in your project and this includes everything of which you likely need none.

If you look at the sources you will find lots of independent projects. 
There exist many gpr files each of which has a file list

    for Source_Files use (...);

Take only what you actually need. Copy the file lists from there and put 
them into your for Source_Files use. This will exclude things you do not 
need. Start with only your files and incrementally add lists from the 
projects containing missing files.

g-socser.ads is the standard AdaCore's GNAT.Sockets package. You must 
have it, if GNAT is installed.

I guess that the actual problem is that it cannot find 
gnat-sockets-server.ads which again dependends on the GNAT compiler 
capabilities. There are 3 incarnations of:

1. Standard Ada in atomic-access/ada

2. Ada incapable of 64-bit atomic access in atomic-access/gcc

3. Ada incapable of 64-bit atomic access yet using 64-bit for stream 
data types. This one is in atomic-access/gcc-long-offsets

On a 64-bit machine it is #1. On a 32-bit machine it is most likely #3.

But, again, you probably do not need any of these.
