Porting my very simple C code from Unixen/macOS to Windows

• RetroBASIC

  2 21 8.9 C

  BASIC interpreter in lex/yacc/c

I have a very simple C console-based program based on flex/bison/c. It uses only standard libraries and has no external dependencies. It compiles on macOS using Xcode or a simple makefile, and appears to work fine on Linux using the same makefile.

• getopt

  7 97 0.0 C

  POSIX getopt() as a portable header library (by skeeto)

Between -std=c99 and removing these headers, you're missing time definitions (struct timeval, gettimeofday) and option parsing definitions (struct option, getopt_long). Mingw-w64 provides all this for compatibility, but MSVC has none of these, so you'll need to write replacements. I've written embeddable, public domain implementations of getopt and something like getopt_long, in case that helps. These are how I deal with option parsing portability.
