AC_DEFINE([GNULIB_STDIO_SINGLE_THREAD], [1],

|
[Define to 1 if you want the FILE stream functions getc, putc, etc.

to use unlocked I/O if available, throughout the package.
|
|
Unlocked I/O can improve performance, sometimes dramatically.
|
|
But unlocked I/O is safe only in single-threaded programs,
|
|
as well as in multithreaded programs for which you can guarantee that
|
|
every FILE stream, including stdin, stdout, stderr, is used only
|
|
in a single thread.])
