The following short program:
/* To see what happens about macros involving chars */
#include <stdio.h>

#define OUTPUT(a) putchar('a')

main(argc, argv)
   int argc;
   char *argv[];
{
   OUTPUT(x);
   return(0);
};

produces the output 
a
under gcc but 
x
under Sun's Solaris 1.1 (Sunos 4.1.3) cc compiler.
This means that /usr/include/ioccom.h will be interpreted differently
for these compilers, in particular the definition:
#define	_IOW(x,y,t)	(_IOC_IN|((sizeof(t)&_IOCPARM_MASK)<<16)|('x'<<8)|y)

How should I proceed with this?
