Set CHEZ environment variable to something that does not start with a slash (/) and compile an application.
Expected Behavior
Either successsfull compilation or nice error about not correct value of the CHEZ env variable
Observed Behavior
Failure during compilation of executable
Now compiling executable <whatever>
Exception in read: invalid syntax #!<value-of-CHEZ-var> at line 1, char 1 of /..../<whatever>.ss
Discussion
Variable CHEZ allows us to say which chez executable is to use in the shebang during the compilation. But its value is used blindly, thus when the value (usually by a mistake) does not start with a slash sign, it is interpreted as a pragma syntax in chez (pragmas in chez also start with #!).
Maybe, we should check at least that value of the CHEZ variable starts with slash, or maybe even that the file exists (but we must be aware of whiltespaces there, which are allowed, strictly speaking).
