Bug 13282 – __libc_current_sigrtmax is not accessible from module linux

Can't use core.sys.posix.signal.SIGRTMIN and core.sys.posix.signal.SIGRTMAX due error: ``` ../../source/daemonize/linux.d(44): Error: function core.sys.posix.signal.__libc_current_sigrtmax is not accessible from module linux ../../source/daemonize/linux.d(44): Error: function core.sys.posix.signal.__libc_current_sigrtmin is not accessible from module linux ``` They are aliases to private functions: ``` private extern (C) nothrow @nogc { int __libc_current_sigrtmin(); int __libc_current_sigrtmax(); } alias __libc_current_sigrtmin SIGRTMIN; alias __libc_current_sigrtmax SIGRTMAX; ``` Workaround: export the functions in your code ``` extern (C) nothrow @nogc { int __libc_current_sigrtmin(); int __libc_current_sigrtmax(); } ``` Checked on dmd 2.065 and 2.066.0-rc2

This was fixed in the meantime - `SIGRTMIN` and `SIGRTMAX` are no longer aliases to a private functions: https://github.com/dlang/druntime/blob/2db828bd4f21807254b770b3ec304f14596a9805/src/core/sys/posix/signal.d#L145-L159
