The problem is basically that sys/ucontext.h is defining R0..R15 which happens to conflict with some packages like Firefox when trying to build on SH. The very same problem existed on arm back then [1] and it was fixed by renaming R0..R15 to REG_R0..REG_R15. This patch imploy a similar strategy for SH. Checked on sh4-linux-gnu with run-built-tests=no and I also got reports that it fixes Firefox build on Debian sh4. * sysdeps/unix/sysv/linux/sh/sh3/ucontext_i.sym: Use new REG_R* constants instead of the old R* ones. * sysdeps/unix/sysv/linux/sh/sh4/ucontext_i.sym: Likewise. * sysdeps/unix/sysv/linux/sh/sys/ucontext.h (NGPREG): Rename... (NGREG): ... to this, to fit in with other architectures. (gpregset_t): Use new NGREG macro. [__USE_GNU]: Remove condition; all architectures other than tile are unconditional. (R*): Rename to REG_R*.
