Most of this is a duplicate of Savannah bug #20501.  The difference in -p output has also been fixed.

To verify this, I ran 3 separate tests:

  • Test 1:
    • Flags used: -p, entered from the command-line
  • Test 2:
    • Flags used: -Rrnp, entered from the command-line
  • Test 3:
    • Flags used: -Rrnp, added to MAKEFLAGS in a makefile



In each case, I ran:

gmake > testN.txt

... then compared them using meld.  Other than adding to MAKEFLAGS in test 3, the makefile was empty.  The results were thus:

  • Test 1: This had the most rules/variables (as you might expect)
  • Test 2: There were no default-rules, and the variables emitted appear to be variables that are part of make's functionality
  • Test 3: There were fewer default rules & variables than test #1, but the number of rules and variables that were emitted far exceeded the number that weren't emitted.


Along these lines, but perhaps only cosmetic:  You get different output if you pass -p on the command-line -vs- adding it to MAKEFLAGS.

I've attached 4 logs demonstrating these issues.
