AC_CHECK_TYPES([errno_t], [], [], [[#include <errno.h>]])
Implement rsize_t / RSIZE_MAX (almost) correctly. The caveat is needed because if you include one of these headers on a system that defines rsize_t without having the correct incantations in your configure.ac, you are going to have a bad time. But there is no good general solution to the problem.

# Components

Differentiate between provider and consumer. Introduce a new macro, CRYB_I_AM, which replaces CRYB_INIT for projects that provide Cryb components or extensions. Currently, the main difference is that they are not required to have the exact same PACKAGE_VERSION as the Cryb version that they use.
2018-11-15 17:10:47 +00:00
CRYB_I_AM
Create autoconf macros to automate component selection. These macros are designed to work in concert with the AX_PKG_CONFIG macros. It is now possible to disable any component, even if another depends on it, provided that it is already installed. For enabled components, we define the same variables as AX_PKG_CONFIG would, so Makefiles don't need to know if a component they rely on is being built as part of this packge or if it was already installed.

Continue to refine our build system. Most importantly, differentiate between library and non-library components. The former can be provided and required, and if provided but disabled, can be replaced by pre-installed versions. The latter can only be provided and cannot be the target of a dependency relationship.
