_POSIX_SOURCE was a POSIX.1-1990 creation that was soon made
obsolete bu _POSIX_C_SOURCE. Retaining mention of it
in the feature test macro requirements section of the
SYNOPSIS doesn't contain important information, and may
mislead readers into actually trying to use this macro.
A few mentions of it a maintained in a some pages where
defining _POSIX_SOURCE inhibits some behavior.
