Uhm, did you really mean to remove that line?
# cat a.asm
%macro m 1
%if %1
%exitmacro
%endif
%endmacro
m 0
m 1
m 2
hlt
# ./nasm -v
NASM version 2.08rc1 compiled on Oct 26 2009

2 %if %1
3 %exitmacro
4 %endif
5 %endmacro

7 m 0
8 <1> %if %1
9 <1> %exitmacro
10 <1> %endif
11 m 1
12 <1> %if %1
13 <1> %exitmacro
14 m 2

16 <1> %exitmacro

The taken %EXITMACRO suppresses all of the "dead"
code after it from appearing in the list file.
Note how the not taken %IF...%ENDIF doesn't do that.
Also, fwiw, I did not require this explicit cond-in-mmac
handling in the code I posted under SF #1842438. So
I am wondering... is it really needed... or just masking
an issue elsewhere in preproc.c?
