Subject: [PATCH] configure: make --disable-threadsafe work
SQLITE_THREADSAFE can be 0, 1 or 2, and if it is not defined, it
is defined to 1 by default in sqlite3.c.
_REENTRANT only needs to be defined or undefined according to
https://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html#Feature-Test-Macros
Forwarded: https://www.mail-archive.com/sqlite-users@mailinglists.sqlite.org/msg115812.html
