the package (including its non-Go source files) will be recompiled.
Note that changes to files in other directories do not cause the package
to be recompiled, so all non-Go source code for the package should be
stored in the package directory, not in subdirectories.
The default C and C++ compilers may be changed by the CC and CXX
