           Milestone:  someday             |  Component:  compiler

-------------------------------------------+----------------------
 The bug I found makes the compiled program unable to locate libraries
 based on the environment variables `CHICKEN_INCLUDE_PATH` and
 `CHICKEN_REPOSITORY_PATH`.

 The bug is quite fiddly to reproduce so I've added a 7z archive that
 contains the neccessary file structure and sets the environment
 variables appropriately. To compile and run it execute the make.sh
 script.

 The program runs as expected as long as the 5. line (exporting the
 macro) in the test.scm file is commented out, but fails to load the
 testlib library if it's included.

 What makes the bug so fiddly and likely the reason why it hasn't been
 noticed so far is that everything works as expected as long as the
 include *.import.scm files and the library *.so files are in the same
 directory, as pointed by CHICKEN_REPOSITORY_PATH. This can be observed
 by commenting out the 8. line in the make.sh script.

 Therefore I hope it's a simple error in using a wrong variable to get
 the search directory for the *.import.scm files.

 Lastly, I've run it on Arch Linux updated as of 2023.03.30:
