Use Gnulib's `getaddrinfo' module.
* m4/gnulib-cache.m4: Add `getaddrinfo'. * libguile/Makefile.am (libguile_la_LDFLAGS): Add `$(GETADDRINFO_LIB) $(HOSTENT_LIB) $(SERVENT_LIB)'.

/* Set up the following warnings, based on which modules are in use.
|
||||
GNU Coding Standards discourage the use of fseek, since it imposes
|
||||
an arbitrary limitation on some 32-bit hosts. Remember that the
|
||||
fseek module depends on the fseeko module, so we only have three
|
||||
cases to consider:
|
||||
|
||||
1. The developer is not using either module. Issue a warning under
|
||||
GNULIB_POSIXCHECK for both functions, to remind them that both
|
||||
functions have bugs on some systems. _GL_NO_LARGE_FILES has no
|
||||
impact on this warning.
|
||||
|
||||
2. The developer is using both modules. They may be unaware of the
|
||||
arbitrary limitations of fseek, so issue a warning under
|
||||
GNULIB_POSIXCHECK. On the other hand, they may be using both
|
||||
modules intentionally, so the developer can define
|
||||
_GL_NO_LARGE_FILES in the compilation units where the use of fseek
|
||||
is safe, to silence the warning.
|
||||
|
||||
3. The developer is using the fseeko module, but not fseek. Gnulib
|
||||
guarantees that fseek will still work around platform bugs in that
|
||||
case, but we presume that the developer is aware of the pitfalls of
|
||||
fseek and was trying to avoid it, so issue a warning even when
|
||||
GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
|
||||
defined to silence the warning in particular compilation units.
|
||||
|
||||
Most gnulib clients that perform stream operations should fall into
|
||||
category three. */
