Question about compiler flags....

[Anonymous]

Ok, actually 2 questions...

If I use a compiler  flag twice in a project file...  For example:

Code: [Select]


CCFLAGS = -Tx86-coff -Ot -Ox -W1 -Gz -Ze -Zx -J #

then later...

  $(CC) $(CCFLAGS) -Ot "$!" -Fo"$@"

(note: -Ot used twice)


Is the effect that of toggling the flag back off in the second occurance? (i.e. is there a way of negating a default flag on a per-file basis?)

Also... if I use two flags that conflict... like -Ot and -Os... in the same type situation, which flag does the compiler use... the first one it finds or the last one it finds?

No toggling, last option used.

Thanks...

(I must still be a bit spoiled from Pascal.  The Borland compiler treats it's flags as toggles... specify something an odd number of times and it's on, an even number of times and it's off.)
