When using gnat to make an ada application, sizeof(pointer) returns 64 bits when it should be 32.

Issue

• When using gnat to make an ada application, sizeof(pointer) returns 64 bits when it should be 32. In addition, this must be made manually by linking in the 32-bit libraries as the default goes directly to the 64-bit libs.
• The 32bit -m32 should compile with gnatmake, the code complies and binds, but the link fails:

bash-4.1$ gnatmake -m32 sizes.adb 
gnatbind -x sizes.ali
gnatlink sizes.ali -m32
