+FUNCTION
+ bfd_put_size
+FUNCTION
+ bfd_get_size
+
+DESCRIPTION
+ These macros as used for reading and writing raw data in
+ sections; each access (except for bytes) is vectored through
+ the target format of the BFD and mangled accordingly. The
+ mangling performs any necessary endian translations and
+ removes alignment restrictions. Note that types accepted and
+ returned by these macros are identical so they can be swapped
+ around in macros---for example, @file{libaout.h} defines <<GET_WORD>>
+ to either <<bfd_get_32>> or <<bfd_get_64>>.
+
+ In the put routines, @var{val} must be a <<bfd_vma>>. If we are on a
+ system without prototypes, the caller is responsible for making
+ sure that is true, with a cast if necessary. We don't cast
+ them in the macro definitions because that would prevent <<lint>>
+ or <<gcc -Wall>> from detecting sins such as passing a pointer.
+ To detect calling these with less than a <<bfd_vma>>, use
+ <<gcc -Wconversion>> on a host with 64 bit <<bfd_vma>>'s.

+ bretheren, except that they are used for removing information
+ for the header records of object files. Believe it or not,
