1) Define the reentrant versions of the syscalls directly.
(eg: _open_r, _close_r, etc.). Please keep the namespace clean.
When you do this, set "syscall_dir" to "syscalls" in configure.in,
and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
When you do this, set "syscall_dir" to "syscalls" and add
-DREENTRANT_SYSCALLS_PROVIDED to newlib_cflags in configure.host.
2) Define namespace clean versions of the system calls by prefixing
them with '_' (eg: _open, _close, etc.). Technically, there won't be
true reentrancy at the syscall level, but the library will be namespace
clean.
When you do this, set "syscall_dir" to "syscalls" in configure.in.
When you do this, set "syscall_dir" to "syscalls" in configure.host.
3) Define or otherwise provide the regular versions of the syscalls
(eg: open, close, etc.). The library won't be reentrant nor namespace
clean, but at least it will work.
When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
configure.in.
When you do this, add -DMISSING_SYSCALL_NAMES to newlib_cflags in
configure.host.
Stubs of the reentrant versions of the syscalls exist in the libc/reent
source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
