# Date 1159379959 0
# Node ID 90d2ef86dc8e9ec203211fc8eded88baa9bc92cb

[lib/ChangeLog]
* __fpending.h: Don't include <stdio_ext.h> unless
HAVE_DECL___FPENDING.  This avoids a bug with lsbcc, where
it causes <stdio_ext.h> to cause a compile-time error.
Problem reported by Nelson H. F. Beebe.
* getpass.c: Likewise, except for HAVE_DECL___FSETLOCKING instead
of HAVE_DECL___PENDING.
[m4/ChangeLog]
* fpending.m4 (gl_FUNC_FPENDING): Check for stdio_ext at most once.
* getpass.m4 (gl_PREREQ_GETPASS): Check for __fsetlocking's declaration.
