I see it both ways. On the one hand, sure Windows vs macOS vs "Linux/BSD" is so very different, you mainly need OS detection. On the other, I don't need a list of the exact featuresets of Fedora, Debian, FreeBSD, NetBSD, OpenBSD, DragonBSD, MorphOS, etc. so I can write narcissism-of-small-differences shit like: #if defined(SUNOS_V4) || defined(_MSC_VER) || defined(GNU) || defined(FREEBSD) # include <strings.h> #else # include <string.h> #endif I will _gladly_ run a feature test and write: #if HAVE_STRINGS_H # include <strings.h> #endif #if HAVE_STRING_H # include <string.h> #endif That is soooooooo much cleaner
