casaroli opened a new pull request, #20534: URL: https://github.com/apache/nuttx/pull/20534
## Summary POSIX declares `strcasecmp()` and `strncasecmp()` in `<strings.h>`. glibc, musl and newlib also declare them in `<string.h>`, and some programs rely on that: they include only `<string.h>` and get an implicit declaration on NuttX. With the new option `CONFIG_LIBC_STRING_STRCASECMP`, `<string.h>` also declares the two functions. Only the prototypes are added; the BSD macros of `<strings.h>` (`bcopy()`, `bzero()` and others) stay out of `<string.h>`. ## Impact New option, default n. Without it nothing changes. ## Testing Builds: `qemu-armv8a:knsh` with and without the option. With it, a file that includes only `<string.h>` and calls `strncasecmp()` compiles without a warning. -- This is an automated message from the Apache Git Service.
