4 Subject: [PATCH 41/42] BUILD: enable poll() by default in the makefile
6 This allows to build haproxy for unknown targets and still have poll().
7 If for any reason a target does not support it, just passing USE_POLL=""

36 To build haproxy, you will need :
37 - GNU make. Neither Solaris nor OpenBSD's make work with the GNU Makefile.
38 However, specific Makefiles for BSD and OSX are provided.
