/* Ported to Win32 by Randy Heit
|
|
* Maybe I got a little carried away. This is pure Win32 code without any CRT in sight.
|
|
*
|
|
* To build this, use one of these command lines:
|
|
*
|
|
* [MinGW] gcc -Os -s -nostdlib -o ccdv.exe ccdv-win32.c -lkernel32 -luser32
|
|
* [MSC] cl -O1 ccdv-win32.c -link -subsystem:console -opt:nowin98 kernel32.lib user32.lib
|
|
*
|
|
* Rewriting this to not use any global variables can save 512 bytes when compiled with MSC
|
|
* because it allows the .data section to be ommitted, which means the header can occupy
|
|
* 512 bytes rather than 1024. With GCC, it doesn't help the size any, since GCC still has
|
|
* the separate .idata and .rdata sections. Since MSC really doesn't need this tool,
|
|
* I'm not bothering with that size optimization.
|
