- A should be a power of two that is at least the type's alignment

- 2**28 on typical GNUish hosts, and 2**13 on MSVC. To be portable
- to MSVC through at least version 10.0, A should be an integer
- constant, as MSVC does not support expressions such as 1 << 3.
- To be portable to Sun C 5.11, do not align auto variables to
- anything stricter than their default alignment.
-
- The following C11 requirements are not supported here:
-
- - If A is zero, alignas has no effect.
- - alignas can be used multiple times; the strictest one wins.
- - alignas (TYPE) is equivalent to alignas (alignof (TYPE)).

AH_VERBATIM([async_safe],
dnl gl_CHECK_FUNCS_ANDROID([func], [[#include <foo.h>]])
dnl is like AC_CHECK_FUNCS([func]), taking into account a portability problem
dnl on Android.
-dnl Namely, if func was added to Android API level, say, 28, then the libc.so
-dnl has the symbol func always, whereas the header file <foo.h> declares func
+dnl
+dnl When code is compiled on Android, it is in the context of a certain
+dnl "Android API level", which indicates the minimum version of Android on
+dnl which the app can be installed. In other words, you don't compile for a
+dnl specific version of Android. You compile for all versions of Android,
+dnl onwards from the given API level.
+dnl Thus, the question "does the OS have the function func" has three possible
+dnl answers:
+dnl - yes, in all versions starting from the given API level,
+dnl - no, in no version,
+dnl - not in the given API level, but in a later version of Android.
+dnl
+dnl In detail, this works as follows:
+dnl If func was added to Android API level, say, 28, then the libc.so has the
+dnl symbol func always, whereas the header file <foo.h> declares func
dnl conditionally:
dnl #if __ANDROID_API__ >= 28
dnl ... func (...) __INTRODUCED_IN(28);
dnl Thus, when compiling with "clang -target armv7a-unknown-linux-android28",
dnl the function func is declared and exists in libc.
dnl Whereas when compiling with "clang -target armv7a-unknown-linux-android27",
-dnl the function func is not declared but exists in libc. We need to treat this
-dnl case like the case where func does not exist.
+dnl the function func is not declared but exists in libc.
+dnl
+dnl This macro sets two variables:
+dnl - gl_cv_onwards_func_<func> to yes / no / "future OS version"
+dnl - ac_cv_func_<func> to yes / no / no
+dnl The first variable allows to distinguish all three cases.
+dnl The second variable is set, so that an invocation
+dnl gl_CHECK_FUNCS_ANDROID([func], [[#include <foo.h>]])
+dnl can be used as a drop-in replacement for
+dnl AC_CHECK_FUNCS([func]).

+/* alignof (TYPE), also known as _Alignof (TYPE), yields the alignment
+ requirement of a structure member (i.e., slot or field) that is of
+ type TYPE, as an integer constant expression.
+
+ This differs from GCC's and clang's __alignof__ operator, which can
+ yield a better-performing alignment for an object of that type. For
+ example, on x86 with GCC and on Linux/x86 with clang,
+ __alignof__ (double) and __alignof__ (long long) are 8, whereas
+ alignof (double) and alignof (long long) are 4 unless the option
+ '-malign-double' is used.
+
+ The result cannot be used as a value for an 'enum' constant, if you
+ want to be portable to HP-UX 10.20 cc and AIX 3.2.5 xlc. */
+
+/* GCC releases before GCC 4.9 had a bug in _Alignof. See GCC bug 52023
+ <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52023>.
+ clang versions < 8.0.0 have the same bug. */

+ aligns the address of FOO and the offset of BAR to be multiples of 8.

+ to MSVC through at least version 10.0, A should be an integer
+ constant, as MSVC does not support expressions such as 1 << 3.
+ To be portable to Sun C 5.11, do not align auto variables to
+ anything stricter than their default alignment.
+
+ The following C23 requirements are not supported here:
+
+ - If A is zero, alignas has no effect.
+ - alignas can be used multiple times; the strictest one wins.
+ - alignas (TYPE) is equivalent to alignas (alignof (TYPE)).
