This test fails. $ dmd -I=imports importd.d importd.d(2): Error: undefined identifier `Have_Qsort_R` importd.d(2): while evaluating: `static assert(Have_Qsort_R)` importd.d ``` import gcc.config; static assert(Have_Qsort_R); ``` imports/gcc/config.d ``` module gcc.config; enum Have_Qsort_R = true; ``` gcc/config.h ``` #ifndef GCC_CONFIG_H #define GCC_CONFIG_H #ifdef GENERATOR_FILE #error config.h is for the host, not build, machine. #endif #ifdef IN_GCC # include "ansidecl.h" #endif #endif /* GCC_CONFIG_H */ ```

The config.h file is found first because config.h appears before config.d in the import search path. If config.h and config.d were in the same directory, the .d file would take precedence.
