One or the other of these patches seems to have caused pmsignal.h
to fail to compile standalone:

./src/include/storage/pmsignal.h:79: error: expected '=', ',', ';', 'asm' or '__attribute__' before
'postmaster_possibly_dead'
./src/include/storage/pmsignal.h: In function 'PostmasterIsAlive':
./src/include/storage/pmsignal.h:84: error: 'postmaster_possibly_dead' undeclared (first use in this function)
./src/include/storage/pmsignal.h:84: error: (Each undeclared identifier is reported only once
./src/include/storage/pmsignal.h:84: error: for each function it appears in.)

Apparently, this header needs a reference to wherever sig_atomic_t
is declared.
