commit 2a81c08b2d867157be6f7f98948c893de594f384

    includes/Stg.h: add declarations for hs_popcnt and frinds
    
    This fixes most of implicit function declarations emitted
    C codegen in UNREG mode. Found by adding the following to
    mk/build.mk:
    
        SRC_CC_OPTS += -Werror=implicit-function-declaration
        SRC_HC_OPTS += -optc-Werror=implicit-function-declaration
    
    Issue #8748
