Using #include <SDL/SDL.h> (or similar) instead of #include <SDL.h> causes
compilation problems in some scenarios on my Gentoo GNU/Linux portage-
multilib system:
checking whether to compile in debug mode... no
checking for SDL... yes
checking for PNG... yes
checking for THEORA... yes
checking for OPENAL... yes
checking for OGGVORBIS... yes
checking for GLee... no
configure: Using integrated GLee
checking for nearbyint in -lm... yes
checking for XSetSelectionOwner in -lX11... yes
checking Xm/Xm.h usability... yes
checking Xm/Xm.h presence... yes
checking for Xm/Xm.h... yes
checking for XmCreateErrorDialog in -lXm... yes

configure: error: SDL OpenGL header not found. Please install SDL with
OpenGL support.
excerpt from config.log:
configure:10103: checking SDL/SDL_opengl.h usability
configure:10103: x86_64-pc-linux-gnu-gcc -std=gnu99 -c -O2 -pipe
-march=athlon64 -g -ggdb -combine -ftree-vectorize -falign-functions=16
-falign-labels=16 -falign-jumps=16 -fstack-protector conftest.c >&5
In file included from /usr/include/SDL/SDL_config.h:4,
from /usr/include/SDL/SDL_opengl.h:25,
from conftest.c:67:
/usr/include/gentoo-multilib/amd64/SDL/SDL_config.h:30:26: error:
SDL_platform.h: No such file or directory
configure:10103: $? = 1
The problem? gentoo-multilib/amd64/SDL/SDL_config.h use #include
"SDL_platform.h" instead of #include <SDL/SDL_platform.h>. Also, this is
Gentoo portage-multilib: since 32-bit and 64-bit code is installed side-
by-side, headers which are different between 32-bit and 64-bit code is
symlinked to different directories. Since /usr/include/SDL is not in CPP's
include path for this configure check like it should be, SDL_config.h
can't find /usr/include/SDL/SDL_platform.h. (SDL_platform.h is ABI-
agnostic, so a copy doesn't also exist in /usr/include/gentoo-multilib-
amd64/SDL ;-) ).
Simply put: The SDL library only makes provisions for
CPPFLAGS=-I/usr/include/SDL and #include <SDL_*.h>. Using #include
<SDL/SDL.h> does cause failures -- under somewhat bizarre circumstances
sometimes I guess ;-). I have seen bug #1683 and I recognize that this is
a bug asking the opposite. But I hope that SDL's upstream FAQ and my
special case are enough to support this patch :-).
