 | Hello, is slib still supporting mzscheme and PLT Scheme?
 | 
 | Using PLT scheme 4.1.0.4, the following message appears during
 | initialization:
 | 
 | /cmp/share/slib/s/slib/mzscheme.init:307:6: if: bad syntax (must have an 
"else" expression) in: (if (provided? (quote trace)) (print-call-stack cep))
 | 
 | mzscheme was called as follows:
 | 
 | SCHEME_LIBRARY_PATH=/cmp/share/slib/s/slib 
/cmp/share/plt-4.1.0.4/i/bin/mzscheme -f /cmp/share/slib/s/slib/mzscheme.init

  (if <test> <consequent>)

is legal syntax in R5RS (and works in MzScheme v372).  If PLT-Scheme
is no longer supporting R5RS, then no; it will no longer run SLIB.

Is 'if' the only incompatibility in plt-scheme-4?  Will someone try
changing forms like:

  (if (provided? (quote trace)) (print-call-stack cep))

to:

  (if (provided? (quote trace)) (print-call-stack cep) #f)

and let us know if it runs.
