66 necessary, because some systems define gettext/textdomain/... in the C

67 library (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer).

68 If we used the unprefixed names, there would be cases where the

69 definition in the C library would override the one in the libintl.so

70 shared library. Recall that on ELF systems, the symbols are looked

71 up in the following order:

72 1. in the executable,

73 2. in the shared libraries specified on the link command line, in order,

74 3. in the dependencies of the shared libraries specified on the link

75 command line,

76 4. in the dlopen()ed shared libraries, in the order in which they were

77 dlopen()ed.

78 The definition in the C library would override the one in libintl.so if

79 either

80 * -lc is given on the link command line and -lintl isn't, or

81 * -lc is given on the link command line before -lintl, or

82 * libintl.so is a dependency of a dlopen()ed shared library but not

83 linked to the executable at link time.

84 Since Solaris gettext() behaves differently than GNU gettext(), this

85 would be unacceptable.

86

87 The redirection happens by default through macros in C, so that &gettext

88 is independent of the compilation unit, but through inline functions in

89 C++, in order not to interfere with the name mangling of class fields or

90 class methods called 'gettext'. */
