11 | # Internally at Concurrent, we use a source management tool which winds up |

12 | # giving us read-only copies of source trees that are mostly symbolic links. |
---|
13 | # That upsets the perl build process when it tries to edit opcode.h and |
---|
14 | # embed.h or touch perly.c or perly.h, so turn those files into "real" files |
---|
15 | # when Configure runs. (If you already have "real" source files, this won't |
---|
16 | # do anything). |
