Question

Occasionally I need to use fixed-width integers for communication with external devices like PLCs. I also use them to define bitmasks and perform bit manipulation of image d

I've used a public domain (not GPL - true public domain) version of stdint.h by Danny Smith that's available in the mingw package:

I had to tweak that version to compile with some non VC 8 compilers (mostly VC6) - it has served me well.

Maybe one of these days I'll get around to posting my VC6-compatible version somewhere. The changes were pretty minor - just some macro trickery to use VC6 specific keywords for 64-bit types. If you don't need VC6 support, the mingw version should probably be all you need.
