	Please not send output of make -d. This is not a makefile's bug but a 
trouble with your system.

	In make output, I see :
libtool: link: gcc -g -O2 -O2 -fno-strict-overflow -malign-double -Wall 
-funsigned-char -Wno-pointer-sign -Wall -g -fno-strict-aliasing 
-Wno-unused -Wno-comment -I/usr/include/freetype2 
-I/usr/include/libpng16 -I/usr/include/freetype2 -I/usr/include/libpng16 
-pthread -o wmluiltok wmluiltok.o  -lfontconfig 
/usr/lib/x86_64-linux-gnu/libfreetype.so -lXft -lpng -pthread
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In 
function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
Makefile:494: recipe for target 'wmluiltok' failed
make: *** [wmluiltok] Error 1

wmluiltok.o was compiled by following command :
gcc -DHAVE_CONFIG_H -I. -I../../include -I../../lib/Xm -I../../lib 
-I./../../lib -I./../../include    -I/usr/include/freetype2 
-I/usr/include/libpng16 -I/usr/include/freetype2 -I/usr/include/libpng16 
  -g -O2  -O2 -fno-strict-overflow  -malign-double -Wall -funsigned-char 
-Wno-pointer-sign -Wall -g -fno-strict-aliasing -Wno-unused -Wno-comment 
-I/usr/include/freetype2 -I/usr/include/libpng16 
-I/usr/include/freetype2 -I/usr/include/libpng16  -MT wmluiltok.o -MD 
-MP -MF .deps/wmluiltok.Tpo -c -o wmluiltok.o wmluiltok.c

	Can you check that wmluiltok.c is not empty ? wmluiltok.c is created by 
flex.

	I have found that flex is faulty on several Linux system. If 
wmluiltok.c is not empty, you have to rebuild flex with 
-ffat-lto-objects option, allowing to use lto also on motif.

	Best regards,
