Subject: Bug?: weak alias fpurge() may better be removed
fpurge() exists as a weak_alias in stdio/ext.c, but it is not
declared in any header files. This causes a problem when building,
for example, zsh:
AC_CHECK_FUNCS(fpurge) finds the alias and defines HAVE_FPURGE,
but compiling a C code using fpurge() fails since it can't be
found in any headers.
It seems fpurge() is removed from stdio.h by an old commit:
a34b0465ba14c70532b8eaba650a9eac228fce57
Is there any reason that the weak_alias needs be kept?
