Both work fine under Win2K pro.

I have tested a DLL on Win{95, 98SE, Me, 2000, XP, Vista} with "data fixups" instead of separated section and it worked on all the mentioned OSes and also in WINE. Also the exports and imports are set with the data directive rather than a separated section for each one. I don't have 16 byte alignment though, but I can't guarantee you that it is not needed (perhaps I'm already aligned in all cases). The type of data that I always needed alignment was "data resource", unless an "align 4" is present before the data directive then depending on whether $ is aligned to 4 or not determines if the program will run correctly (at least on XP).

Doesn't work on Windows 98 SE:
Code:
format pe gui 4.1 dll at 0x00400000
entry DllEntryPoint
include 'win32a.inc'
DllEntryPoint:
mov eax,[esp+0x08]
dec eax
jnz .exit
mov edx,[esp+0x04]
mov [hInstance],edx
stdcall [OutputDebugString],_loaded
.exit:
xor eax,eax
inc eax
retn 0x0c
data import
library kernel32,'KERNEL32.DLL'
include 'api/kernel32.inc'
end data
_loaded db 'DLL is loaded!',0
hInstance dd ?
data fixups
end data

The attached example works for me on Win98SE.
The DLL I was referring to had a code section and a data section and in the latter all the data directories were declared (import, export and fixups). BTW, now I'm not sure if Win95 works because I don't have it on my virtual machines set, perhaps I did the test on my old Cx586 which has Win95 OSR2 as I remember I tested all the Windows versions I had but I cannot test now.
