Installation instructions for SML/NJ under Cygwin ------------------------------------------------- 1. Set SMLNJ_CYGWIN_RUNTIME=1 and export the environment variable. E.g., SMLNJ_CYGWIN_RUNTIME=1 export SMLNJ_CYGWIN_RUNTIME in Bourne sh and variants. Or setenv SMLNJ_CYGWIN_RUNTIME 1 in csh and variants. When this is set SML/NJ will select the Cygwin runtime instead of the default Windows runtime. 2. Simply treat Cygwin as a Unix, and follow the usual installation instructions.
