This is the last invocation of gcc. Make of it what you will!

gcc -D_REENTRANT -D_LARGEFILE64_SOURCE -D__EMX__ -DOS2 -Zmtd 
-D__ST_MT_ERRNO__ -Zexe -O2 -fomit-frame-pointer -Wno-format-y2k 
-Dsh_util -DO_S=\"os/2\" -DSYSCONFDIR=\"/usr/local/etc\" -DHAVE_CONFIG_H 
-IJ:/dev/ncftp-3.1.9 -I../libncftp -I../Strn -I../sio 
-IJ:/dev/ncftp-3.1.9 -IJ:/dev/ncftp-3.1.9/libncftp 
-IJ:/dev/ncftp-3.1.9/sio -IJ:/dev/ncftp-3.1.9/Strn gpshare.o preffw.o 
util.o gl_getline.o version.o ncftpls.c -o ../bin/ncftpls.exe 
-L../libncftp -L../Strn -L../sio -LJ:/dev/ncftp-3.1.9/libncftp 
-LJ:/dev/ncftp-3.1.9/sio -LJ:/dev/ncftp-3.1.9/Strn -Zmtd 
-D__ST_MT_ERRNO__ -O2 -s -Zsysv-signals -Zstack 512 -lcExt -lstcExt 
-lncftp -lStrn -lsio -lsocket

According to the makefile,
CFLAGS=-D_REENTRANT -D_LARGEFILE64_SOURCE -D__EMX__ -DOS2 -Zmtd 
-D__ST_MT_ERRNO__ -Zexe -O2 -fomit-frame-pointer -Wno-format-y2k

There is nothing there for LDFLAGS.

Thanks,
Pete

PS I think the .exe file produced _is_ an a.out file.

IIRC, one should not combine "-Zexe" with "-o something.exe".
Either use "-Zexe -o blub" (and you'll get an empty "blub" and
an executable "blub.exe") _or_ "-o blub.exe", but never
"-Zexe -o blub.exe".

Try, if removing -Zexe does help.
