// Without the -std=c99 option, linux is an implicitly defined macro on Linux
// systems so all such substrings in the given path will be replaced with 1
// during stringification. Unfortunately, Fedora's rpmbuild uses
// x86_64-redhat-linux-gnu as a build directory for all CMake projects which
// leads to a test failure due to an unwanted change to x86_64-redhat-1-gnu.
