Refer to 106.Pa /usr/share/examples/etc/defaults/make.conf 107for a list of recognized 108.Va CPUTYPE 109options. 110.It Va CCVER 111.Pq Vt str 112Controls which GCC version to use by default. 113It should be set as 114.Li CCVER?= 115so as not to interfere with overrides from userland. 116We currently recommend that an override NOT be set in 117.Pa /etc/make.conf . 118Currently accepted values for compilers which are part of 119.Dx 120are 121.Dq gcc41 122and 123.Dq gcc44 124(default). 125All other values will handled according to the settings in 126.Xr compilers.conf 5 . 127.It Va

152.It Va DEBUG_FLAGS 153.Pq Vt str 154Similar to 155.Va CFLAGS 156but it will cause 157.Va STRIP 158to be set to a blank value, if set. 159Typically, 160.Va DEBUG_FLAGS 161is set to 162.Fl g 163for compiling with debug symbols. 164.It Va NO_CPU_CFLAGS 165.Pq Vt str 166Setting this variable will prevent CPU specific compiler flags 167from being automatically added to 168.Va CFLAGS 169during
