Function 'gettid' does not exist on MacOS, dcc use in Mac terminal results in "dcc: Internal error"

[timo-wilson24]

Using MacOS 15.6. I have installed dcc on mac using the installation script as recommended by dcc documentation. When using dcc in the terminal, I get an internal error due to the function 'gettid':

dcc about_me.c -o about_mee
dcc: Internal error
<stdin>:1290:86: error: call to undeclared function 'gettid'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
    snprintf(threadid_buffer, sizeof threadid_buffer, "DCC_SIGNAL_THREAD=%ld", (long)gettid());
                                                                                     ^
1 error generated.

It looks like in wrapper_c/dcc_util.c, on line 254, there is a call to "(long)gettid());".

As far as my research shows, gettid is not a function on macOS, but a similar function is pthread_threadid_np().

Wondering if there is a workaround for me or any way that I can compile dcc with altered source code on my mac so that it uses the above function.

An idea for a long-term solution could be to have an #ifdef __APPLE__ pthread_threadid_np(); #else gettid() (pseudo-code).
