/* This file redirects the gettext functions (without prefix or suffix) to
those defined in the included GNU gettext library (with "__" suffix).
It is compiled into libintl when the included GNU gettext library is
configured --with-included-gettext.
This redirection works also in the case that the system C library or
the system libintl library contain gettext/textdomain/... functions.
If it didn't, we would need to add preprocessor level redirections to
libgnuintl.h of the following form:
How does this redirection work? There are two cases.
A. When libintl.a is linked into an executable, it works because
functions defined in the executable always override functions in
the shared libraries.
B. When libintl.so is used, it works because
1. those systems defining gettext/textdomain/... in the C library
(namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are
ELF systems and define these symbols as weak, thus explicitly
letting other shared libraries override it.
2. those systems defining gettext/textdomain/... in a standalone
libintl.so library (namely, Solaris 2.3 and newer) have this
shared library in /usr/lib, and the linker will search /usr/lib
*after* the directory where the GNU gettext library is installed.
A third case, namely when libintl.a is linked into a shared library
whose name is not libintl.so, is not supported. In this case, on
Solaris, when -lintl precedes the linker option for the shared library
containing GNU gettext, the system's gettext would indeed override
the GNU gettext. Anyone doing this kind of stuff must be clever enough
to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker
command line. */
