Eval buffer in REPL does not emit main(), fails to compile

With reference to examples/arrays.carp

Eval buffer in REPL (bound to C-c C-l in emacs) fails to generate main() in examples/out/main.c causing the clang compile step to fail.

• This is independently reproducible and has been confirmed by @hellerve
• I can call (ex1) and (ex2) from the REPL and they work
• However, calling (main) from the REPL fails and the inferior carp process exits
• The examples/out/main.c file shows ex1() and ex2() generated along with the structs and includes, but does not have main()

I can further confirm that:

• carp -x examples/arrays.carp works and produces the expected output.
• Build-and-run (bound to C-c C-c in emacs) works and produces the expected output, in the inferior Carp process.
• The fat binary generated by build-and-run at example/out/Untitled also successfully runs standalone and produces the expected output.

Thanks for looking into this!

I just want to add that I can confirm this in any Carp REPL, not just in emacs. Calling (main) will result in emitted C code that is missing its main function, weirdly.

I don't know why the issue got closed. I must have fat-fingered something.

I just tried this out... looking good. Thanks!
