With automake, we can do this a lot cleaner with an AM_CONDITIONAL.
Shortened version:

configure.ac:
AM_CONDITIONAL([ENABLE_MOTIF], [test "$enable_motif" = yes])

Makefile.am:
libGLw_la_SOURCES = GLwDrawA.c
libGLw_la_CFLAGS = $(GLW_CFLAGS)
libGLw_la_LIBADD = $(GLW_LIBS)
if ENABLE_MOTIF
libGLw_la_SOURCES += GLwMDrawA.c
libGLw_la_CFLAGS += $(MOTIF_CFLAGS)
libGLw_la_LIBADD += $(MOTIF_LIBS)
endif
