Hello!
libsigsegv currently fails to build from source on sparc64:

handler-unix.c: In function 'sigsegv_handler':
fault-linux-sparc.h:30:70: error: 'mcontext_t {aka struct <anonymous>}' has no
member named 'gregs'
#define SIGSEGV_FAULT_STACKPOINTER ((ucontext_t *)
ucp)->uc_mcontext.gregs[REG_O6]
This is due to the fact that the #define for SIGSEGV_FAULT_STACKPOINTER uses an
outdated
variable name for the gregs member in uc_mcontext. It should be renamed from
"gregs"
to "mc_gregs".
The attached patch does exactly that and fixes the FTBFS on sparc64 and sparc
(V9/V8+).
Please apply the patch to help us with the porting efforts for sparc64.

Description: Fix the definition of SIGSEGV_FAULT_STACKPOINTER for sparc
The definition of SIGSEGV_FAULT_STACKPOINTER uses an outdated variable
identifier for the register window array. sparc V8+ and later renamed
this array from gregs to mc_gregs. This patch fixes an FTBFS.
