+Cross-compiling GLib
+====================
+
+Cross-compilation is the proceess of compiling a program or
+library on a different architecture or operating system then
+it will be run upon. GLib is slightly more difficult to 
+cross-compile than many packages because much of GLib is
+about hiding differences between different systems. 
+
+These notes cover things specific to cross-compiling GLib;
+for general information about cross-compilation, see the
+autoconf info pages.
+
+GLib tries to detect as much information as possible about
+the target system by compiling and linking programs without
+actually running anything; however, some information GLib
+needs is not available this way. This information needs
+to be provided to the configure script via a "cache file"
+or by setting the cache variables in your environment.
+
+As an example of using a cache file, to cross compile for
+the "MingW32" Win32 runtine environment on a Linux system,
+create a file 'win32.cache' with the following contents:
+
+===
+glib_cv_long_long_format=ll
+glib_cv_stack_grows=no
+===
+
+Then execute the following commands:
+
+===
+PATH=/path/to/mingw32-compiler/bin:$PATH
+chmod a-w win32.cache   # prevent configure from changing it
+./configure --cache-file=win32.cache --host=mingw32
+===
+
+The complete list of cache file variables follows. Most
+of these won't need to be set in most cases.
+
+Cache file variables
+====================
+
+glib_cv_long_long_format=[ll/q/I64]
+
+ Format used by printf and scanf for 64 bit integers. "ll" is 
+ the C99 standard, and what is used by the 'trio' library
+ that GLib builds if your printf() is insufficiently capable.
+ Doesn't need to be set if you are compiling using trio.
+
+glib_cv_stack_grows=[yes/no]
+
+ Whether the stack grows up or down. Most places will want "no",
+ A few architectures, such as PA-RISC need "yes".
+
+glib_cv_working_bcopy=[yes/no]
+
+ Whether your bcopy can handle overlapping copies. Only needs to be set 
+ if you don't have memmove. (Very unlikely)
+
+glib_cv_sane_realloc=[yes/np]
+ 
+ Whether your realloc() conforms to ANSI C and can handle NULL as
+ the first argument. Defaults to "yes" and probably doesn't need to be set.
+
+glib_cv_have_strlcpy=[yes/no]
+
+ Whether you have strlcpy that matches OpenBSD. Defaults to "no",
+ which is safe, since GLib uses a built-in version in that case.
+
+glib_cv_va_val_copy=[yes/no]
+ 
+  Whether va_list can be copied as a pointer. If set to "no", 
+  then memcopy will be used. Only matters if you don't have
+  va_copy or __va_copy. (So, doesn't matter for GCC.) Defaults
+  to "yes" which is slightly more common than "no".
+
+glib_cv_rtldglobal_broken=[yes/no]
+ 
+  Whether you have a bug found in OSF/1 v5.0. Defaults to "no".
+
+glib_cv_uscore=[yes/no]
+
+  Whether an underscore needs to be prepended to symbols when
+  looking them up via dlsym. Only needs to be set if your system
+  uses dlopen/dlsym.
+
+ac_cv_func_posix_getpwuid_r=[yes/no]
+
+  Whether you have a getpwuid_r function (in your C library,
+  not your thread library) that conforms to the POSIX spec.
+  (Takes a 'struct passwd **' as the final argument)
+
+ac_cv_func_nonposix_getpwuid_r=[yes/no]
+
+  Whether you have some variant of getpwuid_r that doesn't
+  conform to to the POSIX spec, but GLib might be able to
+  use (or might segfault.) Only needs to be set if 
+  ac_cv_func_posix_getpwuid_r is not set. It's safest to set
+  this to "no".
+
+glib_cv_use_pid_surrogate=[yes/no]
+
+ Whether to use a setpriority() on the PID of the thread as
+ a method for setting the priority of threads. This only
+ needs to be set when using POSIX threads.
+
+ac_cv_func_printf_unix98=[yes/no]
+
+ Whether your printf() family supports Unix98 style %N$
+ positional parameters. Defaults to "no".
+
+ac_cv_func_vsnprintf_c99=[yes/no]
+
+ Whether you have a vsnprintf() with C99 semantics. (C99 semantics
+ means returns the number of bytes that would have been written
+ had the output buffer had enough space.). Defaults to "no".
