* Resurrect <machine/types.h> for <sys/types.h>Sebastian Huber2016-04-211-5/+0
| | | | | | | | | | | Resurrect <machine/_user_types.h> for use in <sys/types.h>. Newlib targets may provide an own version of <machine/types.h> in their machine directory to add custom user types for <sys/types.h>. Check the _SYS_TYPES_H header guard to prevent a direct include of <machine/types.h>, since the <machine/types.h> file is a Newlib speciality.

* Feature test macros overhaul: signal.h (part 2)Yaakov Selkowitz2016-03-181-16/+12
| | | | | | | | | | | Move the sig*set macros following the functions inside their feature test macro conditional. This fixes the build on bare-metal targets following commit 5c78499ae2ae6ac28854b43a1ad73d917b40c62d.

* Feature test macros overhaul: signal.hYaakov Selkowitz2016-03-171-13/+6
| | | | | | | | | | | | Use proper internal macros for BSD sig_t and GNU sighandler_t. sigaltstack and friends are XSI even in SUSv4 but in glibc are nonetheless handled as POSIX.1-2008 (not 2001). The requirement for the ucontext_t typedef in signal.h was XSI prior to POSIX.1-2008. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* FreeBSD compatibility for <sys/select.h>Sebastian Huber2015-12-141-3/+4
| | | | | | | | | | | | * libc/include/sys/_sigset.h: New. * libc/include/sys/select.h: Do not include <sys/types.h> and <sys/time.h> to avoid cyclic header file dependencies. Include specialized header files instead. (sigset_t): Conditionally define. * libc/include/sys/signal.h (sigset_t): Likewise. * libc/include/sys/time.h: Include <sys/select.h> if __BSD_VISIBLE. * libc/include/sys/types.h: Likewise.
* Always declare "kill" in include/sys/signal.hJames Greenhalgh2015-08-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Hi, As I mentioned recently [1], newlib is providing a "kill" symbol to link against, without declaring "kill" in signal.h. This is confusing for the libgfortran build, which tries to link against kill (which succeeds), then tries to use it (which triggers -Werror=implicit-function-declaration). This patch implements my suggestion in that thread - making the declaration of 'kill' in libc/include/sys/signal.h unconditional. I've tested this by building a modified libgfortran on AArch64/ARM to see that the Werror goes away, and the libgfortran build succeeds. Is something like this OK for newlib? If so, can someone please commit it on my behalf, as I have no commit access here. Otherwise, what is your preferred direction for me to take this patch? Thanks, James
