Useful for "TestCompile sizeof" +# and "TestCompile byteorder" tests. +# Otherwise, TestCompile only tests for the presence of a +# generated program when deciding whether the compilation was +# successful. +# +# $TCADDINCL (#include <> stmt list; default=empty) +# If set to an "#include <file>" preprocessor directive +# (optionally several #include's separated by newlines), these +# directives will be added to the generated test sources. +# That allows, e.g., the "TestCompile sizeof" test to check for +# types which are not defined in the standard locations. +# +# $TLIB (additional libraries; default=empty) +# If set to a list of additional libraries, these libs will be used +# in addition to the one tested by the "TestCompile lib" call. +# For the other TestCompile tests, it is ignored. +# +# +# Initially written by Jim Jagielski for the Apache configuration mechanism +# +# This script falls under the Apache License. +# See http://www.apache.org/docs/LICENSE + + +cd ./helpers + +# +# Handle "verbose", "silent" and "runit" flags.
