Rich Felker	47e72e10d5	avoid errors in ucontext.h when no feature test macros are defined	2011-06-29 17:13:01 -04:00
Rich Felker	ad2fe25041	support the ugly and deprecated ucontext and sigcontext header stuff... ... only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on...	2011-02-18 22:03:03 -05:00
Rich Felker	798a12ecc4	ucontext is no longer in the standard, so use gnu-friendly struct name ... note that this header is still bogus and needs a lot of work and factoring into arch-dependent parts...	2011-02-16 23:36:26 -05:00
