 * `-Wextra`: turns on even more warnings, but still not all.
 * `-Wcast-align`: warn whenever a pointer is cast such that the required alignment is increased (`char*` -> `int*`).
 * `-Wcast-qual`: warn when qualifier (`cosnst`) is cast away, or introduces a qualifier in an unsafe way.
-* `-Wdisabled-optimization`: warn if a requested optimization pass is disable.
+* `-Wdisabled-optimization`: warn if a requested optimization pass is disabled (e.g. code is too large, has some other feature that makes g++ give up).
 * `-Wduplicated-branches`: warn if if-else branches have identical bodies.
 * `-Wduplicated-cond`: warn about duplicated conditions in an if-else-if chain.
 * `-Wformat=2`: same as `-Wformat` `-Wformat-nonliteral` `-Wformat-security` `-Wformat-y2k`. make sure printf-style function arguments match their format strings.
