only for Borland C. For Watcom they are not duplicated (only one CS: there). And anyway it's only a small amount of code. > Of course, initial efforts to implement are not very easy, but gain is > noticeable.

Watcom generated NEAR calls to these functions. Relocation wouldn't help. This point is moot now with one CS, and anyway I like our own versions better :) > The more > so, now they may be moved from low/nonrelocatable part (in kernel.asm) into > resident part! (Do you remember, how I was try to move Borland's RTL > functions into resident part and forget about relocations?) Yes you could move these into the resident part if you do runtime patching. But is it worth the effort for a secondary compiler? I will not stop you trying to do this, but I see it as a waste of time myself (other than an exercise in patching). > >> PS: Bart, some time ago you decrease kernel by reordering object files.

I remeber something about reduced executable size, > but without words about compression. No it was only compression, how else can reordering save space? The trick to reduce uncompressed executable size was only obtained using a different default calling convention via #pragma.
