even @C_FALSE@ (unsatisfied) contains rule to produce binary

[Jan Kratochvil]

Hi,

it came on now on the binutils mailing list:

The "a" program gets built only `if F' below.  Makefile.in correctly contains:
@address@hidden: b.c
@F_TRUE@        gcc -o $@ $< -Wall

But while does it also contains:
@address@hidden(EXEEXT): $(a_OBJECTS) $(a_DEPENDENCIES)
@F_FALSE@       @rm -f a$(EXEEXT)
@F_FALSE@       $(LINK) $(a_OBJECTS) $(a_LDADD) $(LIBS)

which does not work anyway as $(a_OBJECTS) is not defined in @address@hidden

Posting here for a consideration as asked about by Ralf Wildenhues.


Thanks,
Jan
