Subject: [PATCH] qga/commands: Include proper Solaris header for getloadavg()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Solaris declares getloadavg() in <sys/loadavg.h>:

    getloadavg(3C)       Standard C Library Functions       getloadavg(3C)

    NAME
           getloadavg - get system load averages

    SYNOPSIS
           #include <sys/loadavg.h>

           int getloadavg(double loadavg[], int nelem);

    [...]

    Oracle Solaris 11.4           23 Jul 2020               getloadavg(3C)

Include it in order to avoid:

  ../qga/commands-posix.c: In function 'qmp_guest_get_load':
  ../qga/commands-posix.c:1408:9: error: implicit declaration of function 'getloadavg' [-Wimplicit-function-declaration]
   1408 |     if (getloadavg(loadavg, G_N_ELEMENTS(loadavg)) < 0) {
      |         ^~~~~~~~~~
  ../qga/commands-posix.c:1408:9: warning: nested extern declaration of 'getloadavg' [-Wnested-externs]

../configure relevant output:

  C compiler for the host machine: gcc (gcc 14.2.0 "gcc (GCC) 14.2.0")
  C linker for the host machine: gcc ld.solaris 5.11-1.3315
