Yes, I tried and the result is below.

function bootStringToStruct (bootString : Interfaces.C.Strings.chars_ptr;
                                pBootParams : access BOOT_PARAMS)
                                   return Interfaces.C.Strings.chars_ptr;
pragma Import (CPP, bootStringToStruct,  "_Z18bootStringToStructPcP11BOOT_PARAMS");

Why was "_Z18bootStringToStructPcP11BOOT_PARAMS" generated for third parameter of pragma Import? I thought it should be "bootStringToStruct".
