Details:
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.
