.B \-\-change\-leading\-char
Some object file formats use special characters at the start of
symbols. The most common such character is underscore, which compilers
often add before every symbol. This option tells
.B objcopy
to change the leading character of every symbol when it converts
between object file formats. If the object file formats use the same
leading character, this option has no effect. Otherwise, it will add
a character, or remove a character, or change a character, as
appropriate.
.TP
.B \-\-remove\-leading\-char
If the first character of a global symbol is a special symbol leading
character used by the object file format, remove the character. The
most common symbol leading character is underscore. This option will
remove a leading underscore from all global symbols. This can be useful
if you want to link together objects of different file formats with
different conventions for symbol names.
remove a leading underscore from all global symbols. This can be
