* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-2313-27/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Remove unused and unsafe call to __builtin_frame_addressPeter Foley2016-03-201-3/+2
| | | | | | | | | | | | | | | | initial_sp has been unused since commit fbf23e3 back in 2000. Keep the value, so as to avoid changing the offset of magic_biscuit. winsup/cygwin/lib/_cygwin_crt0_common.cc:140:52: error: calling 'void* __builtin_frame_address(unsigned int)' with a nonzero argument is unsafe [-Werror=frame-address] u->initial_sp = (char *) __builtin_frame_address (1); winsup/cygwin/ChangeLog lib/_cygwin_crt0_common.cc (_cygwin_crt0_common): Initialize initial_sp with nullptr.
