Because if function foo's third flag parameter supports FOO_ENABLE_FEATURE_X starting from 2.31, and a program only occasionally calls foo with this flag, there is no good way to detect this incompatibility on a 2.30 system at link time. The restriction is only annoying because there is no way to trivially link against an older "minimum requirement" ABI. |
