getting a handle on build warnings

FYI...
I dug up my old wstats ksh script and ran it over a concatenation of the
latest jdk7 build 30 logs for all 8 of builds done by Java Release Engineering
(solaris-i586, solaris-x64, solaris-sparc, solaris-sparcv9, linux-i586,
linux-x64, windows-i586, and windows-x64).
Granted, these are OLD Linux systems with gcc 3.2, and lots of duplicates
here.
The problems with dealing with the C/C++ warnings is that the different compilers
and different releases of the compilers create a bit of an unknown when trying
to fix warnings. Fixing a warning from gcc4 might just trigger a new warning
for some other reason from the Sun Studio compiler, can be frustrating.
And using just a slightly newer or patched gcc or Sun Studio compiler might
generate new warnings you haven't seen before.
This has gotten better over time but continues to be an issue.
A danger also lies in how a warning is fixed in native code that needs to work on
all platforms and with different compilers, for example, adding a cast like
'(long)' might shut up a warning, but could break Windows X64 where a long
is 32bits not 64bits. People need to be very careful in the native code.
At least with the javac warnings, fixing them is more concrete, and probably
less risky ;^)
I'm all in favor of fixing the warnings, just trying to make sure it's done
safely. ;^)
