Hello List,

I need to create a list with some valid values and check an input
value. Should this makefile work?
-----
LIST=f8 f9

all:
        @echo USE_LINUX=${USE_LINUX}, LIST=${LIST}
.if empty(LIST:M${USE_LINUX})
        @echo The value is invalid
.else
        @echo The value is valid
.endif
-----
% make USE_LINUX=f8
USE_LINUX=f8, LIST=f8 f9
The value is invalid
-----


WBR
