.B -Wlocal-shadows
Warn when a locally declared variable shadows variable.
Warn about global variables with no initializing value. This is off by

supposed to be replaced by the untyped 'nil' constant.

+Similar to the above but for attributes like "[[noreturn]]".

+Warn when a function is marked with the attribute

+Warn about possible mistakes caused by missing or wrong parenthesis,

+Note that this is different from fteqcc's __NULL__ in that gmqcc
+generates an actual empty global, rather than using the global at
+offset 0 because it would overlap with the global RETURN variable when
+dealing with vectors, which starts at offset 1. Setting a vector to
+__NULL__ in fteqcc causes only the vector's x component to be 0.
+However, its y and z components will contain the previous x and y
+components of the global OFS_RETURN.

+.B -Ovector-components
+Because traditional QC code doesn't allow you to access individual
+vector components of a computed vector without storing it in a local
+first, sometimes people multiply it by a constant like '0 1 0' to get,
+in this case, the y component of a vector. This optimization will turn
+such a multiplication into a direct component access. If the factor is
+anything other than 1, a float-multiplication will be added, which is
+still faster than a vector multiplication.
