cypherpunks	be080a402f	Replace obsolete macros with modern equivalents	2016-12-23 10:34:11 -05:00
cypherpunks	94762e37b9	Use the Autoconf macro AC_USE_SYSTEM_EXTENSIONS ... The Autoconf macro AC_USE_SYSTEM_EXTENSIONS defines preprocessor macros which turn on extensions to C and POSIX. The macro also makes it easier for developers to use the extensions without needing (or forgetting) to define them manually. The macro can be safely used because it was introduced in Autoconf 2.60 and Tor requires Autoconf 2.63 and above.	2016-06-17 10:17:44 -04:00
Nick Mathewson	2662885aa9	Use pc_from_ucontext.m4 from Google Performance Tools ... This M4 module lets us learn the right way (out of at least 18 possibilities) to extract the current PC for stack-trace-fixup-in-signal purposes. The Google Performance Tools license is 3-clause BSD.	2013-11-18 10:43:15 -05:00
