GENERAL.sml (referenced in 'basis-1997.mlb') does not exist or cannot be read

[serpent7776]

I have a trivial test.mlb file containing single line:

$(SML_LIB)/basis/basis-1997.mlb

I can successfully compile this with mlton test.mlb, but mlkit test.mlb gives an error:

* Error: The file '/work/mlkit//basis/GENERAL.sml' (referenced in 'basis-1997.mlb') does not exist or cannot be read.
* Exiting!

It works fine when I use

$(SML_LIB)/basis/basis.mlb

I'm running this on FreeBSD. Maybe there's an issue with case-sensitivity, because there is file basis/General.sml, but no basis/GENERAL.sml.
Tested on 05d7384 and 86c9cb8

The problem is due to a renaming of many of the files containing signatures; these have been changed to have extension .sig, which allows them to have the same base name as the files containing implementation code...
