--- Comment #29 from Hamlet <_hamlet at libero dot it> ---
For what it's worth, I confirm this (and bug 70888) with gcc 6.3.0 from
Gentoo/Linux.
In particular, the following program ("test.cpp"):
#pragma GCC diagnostic ignored "-Wlong-long"
const unsigned long long int ticks_per_day = 86400000000LL;
compiled with `g++-6.3.0 -c -std=c++03 -pedantic -Werror test.cpp` (C++03
standard) issues an error:
test.cpp:2:46: error: use of C++11 long long integer constant
[-Werror=long-long]
const unsigned long long int ticks_per_day = 86400000000LL;
^~~~~~~~~~~~~
about the long long literal value, while it correctly suppresses the one about
the variable itself. Skipping the preprocessor (`-fpreprocessed`) does not
affect the outcome (the preprocessor correctly leaves the `#pragma` directive
untouched anyway).
Using `-Wno-long-long` in the command line instead works as expected (but it's
not a viable solution when dealing with third party libraries).
Info on GCC:
Using built-in specs.
