+
+ Improve testsuite diagnostic message handling.
+
+ * include/process.h [__IN_MINGWRT_TESTSUITE__ && __GNUC__ >= 7]: Push
+ diagnostic state, to save the initial setting of, and then ignore...
+ (-Wbuiltin-declaration-mismatch): ...this, prior to declarations of...
+ (execv, execve, execvp): ...these functions; after these declarations,
+ pop the saved diagnostic state, to revert to the original condition,
+ rather than simply, and arbitrarily, enabling the warning.
+
+2022-08-26 Keith Marshall <keith@users.osdn.me>
+
+ Do not expose private declarations in <search.h>

+ (_SEARCH_PRIVATE): Remove definition; it is no longer required.
+
+2022-08-15 Keith Marshall <keith@users.osdn.me>

+
+ Stop creating redundant "include/parts" directory.
+

+2021-01-26 Keith Marshall <keith@users.osdn.me>
+
+ Avoid proliferation of static snprintf() implementations.
+
+ * mingwex/dlfcn.c (dlfcn_store_error_message): Do NOT use...

+ directly, to avoid code redundancy.

+
+ Add support for emulation of Microsoft's rand_s() function.
+
+ * mingwex/cryptnam.c (crypto_provider, crypto_randomize): Factor out
+ this pair of static inline functions; relocate them to...
+ * mingwex/memcrypt.c: ...this new file.
+ (crypto_randomize): Change linkage to extern; rename it as...
+ (__mingw_crypto_randomize): ...this; use it...
