// It stores in the directory the dependency and compiler options to
// regenerate the template code if necessary. Unfortunately, it stores the
// option -D__OSVERSION__=5 as -D__OSVERSION__='5'. This of course causes
// the compilation to fail because the source code assume that the CPP macro
// __OSVERSION__ is an interger. The following hack detects this condition
// and revert the macro to its expected form.
