I recently ran into problems when compiling a matrix library containing
a function called "minor". Apparently, the file
/usr/include/sys/sysmacros.h has the following definitions:
#ifdef __CYGWIN_USE_BIG_TYPES__
#define major(dev) ((int)(((dev) >> 16) & 0xffff))
#define minor(dev) ((int)((dev) & 0xffff))
#define makedev(major, minor) (((major) << 16) | ((minor) & 0xffff))
#else
#define major(dev) ((int)(((dev) >> 8) & 0xff))
#define minor(dev) ((int)((dev) & 0xff))
#define makedev(major, minor) (((major) << 8) | ((minor) & 0xff))
#endif
Defining macros with names like "major" and "minor" is really not good,
IMO. This should probably be changed, if possible.
