We were duplicating the Unicode/code page mapping table between
txt_gui.c and txt_sdl.c, but in an incomplete and inconsistent way. It
makes sense that the code page mapping should be kept with the font
files that represent the code page anyway, as there may be projects like
Julian Nechaevsky's Russian Doom which may want to change the code page.
The source and destination arguments to memcpy() cannot be overlapping
as this is undefined behavior. In these situations memmove() must be
used instead, and OpenBSD actually throws an error if this is done.
Thanks to ryan-sg for reporting this. This fixes#510.
This change rewrites and simplifies the copyright headers at the top
of all source files:
* Remove "Emacs style mode select" line; this line was included in
the headers for the originally released source files and appears
to be to set the file type for old versions of Emacs. I'm not sure
entirely why it was required but I don't think it is any more.
* Remove "You should have received a copy of..." text from copyright
header. This refers to the old 59 Temple Place address where the
FSF headquarters used to be located and is no longer correct.
Rather than change to the new address, just remove the paragraph
as it is superfluous anyway. This fixes#311.
* Remove ---- separator lines so that the file headers are barer
and more simplified.
