[fpc-pascal] set envirom variable with pascal in linux

[mondrillo]

Thanks, is the only think that I probe and runs ok!!!

****
program shell2;

uses baseunix, sysutils;
begin
    writeln('glx-config Version:',fpGetenv('SDL_VER'));
end.
****

export SDL_VER=`sdl-config --version`; ./shell2
glx-config Version:1.2.8

Note. I have put the clause EXPORT because I'm using bash.

I don't probe tu use the other method that other person has posted than
use a call to glibc, perhaps it's the largest walk. 

Another one, has mentioned than FreePascal(FP) gives an enviroment in
read-only, I have read that the environ is an array of list of var's
with values, and I'dont know why FP (I love it) cannot write in this
array, perhaps do not implement yet.

Thank's eveybody, and regards.
