Configure check to see if the compiler works.
Note that this uses the current value of compiler and linker flags, make
sure $CFLAGS, $CPPFLAGS and $LIBS are set correctly.
"language" should be "C" or "C++" and is used to select the compiler.
Default is "C".
"text" may be used to specify the code to be build.
Returns an empty string for success, an error message for failure.

Configure check for a function "function_name".
"language" should be "C" or "C++" and is used to select the compiler.
Default is "C".
Optional "header" can be defined to define a function prototype, include a
header file or anything else that comes before main().
Sets HAVE_function_name in context.havedict according to the result.
Note that this uses the current value of compiler and linker flags, make
sure $CFLAGS, $CPPFLAGS and $LIBS are set correctly.
Returns an empty string for success, an error message for failure.

S( sz This check can be used to get the size of a given type, or to check whether
the type is of expected size.
Arguments:
- type : str
the type to check
- includes : sequence
list of headers to include in the test code before testing the type
- language : str
'C' or 'C++'
- expect : int
if given, will test wether the type has the given number of bytes.
If not given, will automatically find the size.
Returns:
status : int
0 if the check failed, or the found size of the type if the check succeeded.s

Use the same test as autoconf, that is test whether the symbol is defined
as a macro or can be used as an r-value.
Arguments:

Configure check for a C or C++ libraries "libs". Searches through
the list of libraries, until one is found where the test succeeds.
Tests if "func_name" or "call" exists in the library. Note: if it exists
in another library the test succeeds anyway!
Optional "header" can be defined to include a header file. If not given a
default prototype for "func_name" is added.
Optional "extra_libs" is a list of library names to be added after
"lib_name" in the build command. To be used for libraries that "lib_name"
depends on.
Optional "call" replaces the call to "func_name" in the test code. It must
consist of complete C statements, including a trailing ";".
Both "func_name" and "call" arguments are optional, and in that case, just
linking against the libs is tested.
"language" should be "C" or "C++" and is used to select the compiler.
Default is "C".
Note that this uses the current value of compiler and linker flags, make
sure $CFLAGS, $CPPFLAGS and $LIBS are set correctly.
Returns an empty string for success, an error message for failure.

Handle the result of a test with a "yes" or "no" result.
"ret" is the return value: empty if OK, error message when not.
"key" is the name of the symbol to be defined (HAVE_foo).
"text" is the source code of the program used for testing.
"comment" is the C comment to add above the line defining the symbol (the
comment is automatically put inside a /* */). If None, no comment is added.

Store result of a test in context.havedict and context.headerfilename.
"key" is a "HAVE_abc" name. It is turned into all CAPITALS and non-
alphanumerics are replaced by an underscore.
The value of "have" can be:
1 - Feature is defined, add "#define key".
0 - Feature is not defined, add "/* #undef key */".
Adding "undef" is what autoconf does. Not useful for the
compiler, but it shows that the test was done.
number - Feature is defined to this number "#define key have".
Doesn't work for 0 or 1, use a string then.
string - Feature is defined to this string "#define key have".
Give "have" as is should appear in the header file, include quotes
when desired and escape special characters!

Convert a language name to a suffix.

Returns a tuple (lang, suffix, None) when it works.
For an unrecognized language returns (None, None, msg).
Where:
lang = the unified language name
suffix = the suffix, including the leading dot
msg = an error message
