This build error came while building on musl /w clang-16.
In contrast to glibc, musl is not having the "legacy" BSD functions and only POSIX sigprocmask.
The exact error was:
sig_block.c:15:3: error: call to undeclared function 'sigblock'; ISO C99 and later do not
support implicit function declarations [-Wimplicit-function-declaration]
sigblock(1 << (sig - 1));
^
sig_block.c:15:3: note: did you mean 'sig_block'?
sig_block.c:7:6: note: 'sig_block' declared here
void sig_block(int sig)
^
1 warning generated.
sig_block.c:27:3: error: call to undeclared function 'sigsetmask'; ISO C99 and later do not
support implicit function declarations [-Wimplicit-function-declaration]
sigsetmask(sigsetmask(~0) & ~(1 << (sig - 1)));
^
sig_block.c:38:3: error: call to undeclared function 'sigsetmask'; ISO C99 and later do not
support implicit function declarations [-Wimplicit-function-declaration]
sigsetmask(0);

This patch should fix the error
