<pre>I'm using tup as my build system on linux.
Tup does some things different as more traditional build systems like make,
specifically it handles out of source builds via a temporary fuse folder.
This however, breaks debug info when compiling out of source, as it points to a
non-existent folder.
On the Tup google user groups a user came up with a solution to use GCC's
-fdebug-prefix-map option to fix the path to the source. As can be seen here:
<a href="https://groups.google.com/d/msg/tup-users/LggFabs7Iwo/FrZ4ZTn1CjwJ">https://groups.google.com/d/msg/tup-users/LggFabs7Iwo/FrZ4ZTn1CjwJ</a>
In short, making this option public will allow me (and other tup users) to have
debug info working as expected.</pre>
