The long list of architectures in include/curl/system.h is annoying to maintain, and needs to be extended for each and every architecture to support. Instead, let's rely on the __SIZEOF_LONG__ define of the gcc compiler (we are in the GNUC condition anyway), which tells us if long is 4 bytes or 8 bytes. This fixes the build of libcurl 7.55.0 on architectures such as OpenRISC or ARC. Closes #1766 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |

Include files for libcurl, external users.
They're all placed in the curl subdirectory here for better fit in any kind
of environment. You must include files from here using...
#include <curl/curl.h>
... style and point the compiler's include path to the directory holding the
curl subdirectory. It makes it more likely to survive future modifications.
NOTE FOR LIBCURL HACKERS
* If you check out from git on a non-configure platform, you must run the
appropriate buildconf* script to set up files before being able of compiling
the library.
* We cannot assume anything else but very basic compiler features being
present. While libcurl requires an ANSI C compiler to build, some of the
earlier ANSI compilers clearly can't deal with some preprocessor operators.
* Newlines must remain unix-style for older compilers' sake.
* Comments must be written in the old-style /* unnested C-fashion */
To figure out how to do good and portable checks for features, operating
systems or specific hardwarare, a very good resource is Bjorn Reese's
