- fix internal macro `AN_APPLE_OS` reused between sources without
resetting it. It may potentially have left the system sha256
function unused.
- fix to define `WOLFSSL_OPTIONS_IGNORE_SYS` so that it always applies
to wolfSSL headers, also during feature detection.
- md4, md5, sha256: simplify fallback logic.
- delete 20+ unused macros.
- scope or move macros to avoid `-Wunused-macros` warnings.
- examples: delete unused code.
The warning detects macros defined but not used within the same C
source. It does not warn for macros defined in headers. It also works
with unity builds, but to a lesser extent.
Closes#20593
- curl_setup.h: replace `_CRT_SECURE_NO_DEPRECATE` with
`_CRT_SECURE_NO_WARNINGS`, which seems to be the preferred,
more recent macro for this. Also syncing with libssh2.
They are equivalent for curl sources with the supported compilers.
- cmake: stop setting `_CRT_SECURE_NO_DEPRECATE` globally for examples.
- examples: suppress CRT deprecation warnings on a per-file basis.
To make it work when compiling examples out of curl's build systems.
Use `_CRT_SECURE_NO_WARNINGS`.
- examples: document the functions requiring `_CRT_SECURE_NO_WARNINGS`.
- examples/block_ip: delete superfluous `_CRT_SECURE_NO_WARNINGS`.
- examples/block_ip: limit `_CRT_NONSTDC_NO_DEPRECATE` to MSVC.
- examples/log_failed_transfers: fix to set `_CRT_SECURE_NO_WARNINGS`
before headers and limit to MSVC.
- curl_setup.h: document which SDKs support `_CRT_NONSTDC_NO_DEPRECATE`.
Closes#19175
Windows CE support was limited to successful builds with ming32ce
(a toolchain that hasn't seen an update since 2009, using an ancient gcc
version and "old mingw"-style SDK headers, that curl deprecated earlier).
Builds with MSVC were broken for a long time. mingw32ce builds were never
actually tested and runtime and unlikely to work due to missing stubs.
Windows CE toolchains also miss to comply with C89. Paired with lack of
demand and support for the platform, curl deprecated it earlier.
This patch removes support from the codebase to ease maintaining Windows
codepaths.

- badwords.pl: add `-a` option to check all lines in source code files.
Before this patch indented lines were skipped (to avoid Markdown code
fences.)
- GHA/checksrc: use `-a` when verifying the source code.
- GHA/checksrc: disable `So` and `But` rules for source code.
- GHA/checksrc: add docs/examples to the verified sources.
- badwords.txt: delete 4 duplicates.
- badwords.txt: group and sort contractions.
- badwords.txt: allow ` url = `, `DIR`, `<file name`.
Closes#19536
- 'CURL *' handles are called 'curl'
- 'CURLM *' handles are called 'multi'
- write callbacks are called 'write_cb'
- read callbacs are called 'read_cb'
- CURLcode variables are called 'res'
It makes the examples look and feel more consistent. It allows for
easier copy and pasting between examples.
Closes#19299
- add `curl_global_init()` and `curl_global_cleanup()` where missing.
- check the result of `curl_global_init()` where missing.
- return the last curl error from `main()`.
- drop Win32-specific socket initialization in favor of `curl_global_init()`.
- rename some outliers to `res` for curl result code.
- fix cleanup in some error cases.
Inspired by Joshua's report on examples.
Closes#19053
- include `windows.h` after `winsock2.h` via `curl/curl.h`.
- avoid `errno` for WinCE.
- avoid `_vscprintf` for WinCE.

- Add an example that demonstrates per-transfer verbose logging to
memory.
The transfer's log is written to disk only if the transfer fails.
