1179 particular, are NOT async-signal-safe.
1180 * All memory locations (variables and struct fields) that these functions
1181 access must be marked 'volatile'. This holds for both read and write
1182 accesses. Otherwise the compiler might optimize away stores to and
1183 reads from such locations that occur in the program, depending on its
1184 data flow analysis. For example, when the program contains a loop
1185 that is intended to inspect a variable set from within a signal handler
1186 while (!signal_occurred)
1187 ;
1188 the compiler is allowed to transform this into an endless loop if the

1191 * A signal handler should not modify errno (except if it is a handler
1192 for a fatal signal and ends by raising the same signal again, thus
1193 provoking the termination of the process). If it invokes a function
1194 that may clobber errno, it needs to save and restore the value of

1201 Suppress extern inline with HP-UX cc, as it appears to be broken; see
1202 <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
1203
1204 Suppress extern inline with Sun C in standards-conformance mode, as it
1205 mishandles inline functions that call each other. E.g., for 'inline void f
1206 (void) { } inline void g (void) { f (); }', c99 incorrectly complains
1207 'reference to static identifier "f" in extern inline function'.
1208 This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
1209
1210 Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
1211 on configurations that mistakenly use 'static inline' to implement
1212 functions or macros in standard C headers like <ctype.h>. For example,
1213 if isdigit is mistakenly implemented via a static inline function,
1214 a program containing an extern inline function that calls isdigit
1215 may not work since the C standard prohibits extern inline functions
1216 from calling static functions (ISO C 99 section 6.7.4.(3).
1217 This bug is known to occur on:
1218
1219 OS X 10.8 and earlier; see:
1220 https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
1221
1222 DragonFly; see
1223 http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
1224
1225 FreeBSD; see:
1226 https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
1227
1228 OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
1229 for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
1230 Assume DragonFly and FreeBSD will be similar.
1231
1232 GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
1233 inline semantics, unless -fgnu89-inline is used. It defines a macro
1234 __GNUC_STDC_INLINE__ to indicate this situation or a macro
1235 __GNUC_GNU_INLINE__ to indicate the opposite situation.
1236 GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
1237 semantics but warns, unless -fgnu89-inline is used:
1238 warning: C99 inline functions are not supported; using GNU89
1239 warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
1240 It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.
