#139 CSL Reduce 6183 compilation fails on macOS 10.15 x86_64

[Marco Ferraris]

Compiling CSL Reduce revision 6183 fails with the following error message:

In file included from ~/sw/reduce-algebra/trunk/csl/fox/src/FXTerminal.cpp:88:
~/sw/reduce-algebra/trunk/csl/fox/include/termed.h:92:14: error: no type named 'at_exit' in namespace 'std'
std::at_exit(term_close);

The system info is: x86_64-mac_10.15_catalina-darwin19.6.0

Best regards

I believe this was corrected in r6184
