/usr/ccs/lib/cpp is not conforming to an official C standard but it is the
standard K&R cpp from 30 years ago.
Platforms that do not have a UNIX history in background today do not deliver
a K&R cpp anymore.
You may get a similar behavior woth gcc's cpp if you use -traditional-cpp.
This still gives a different output.... As cpp is non-free, SchilliX pipes the
outpout from gcc-cpp -traditional-cpp though /usr/lib/cpp-post which has been
written to convert ANSI cpp output to something that looks similar to K&R cpp.
#include <schily/mconfig.h>
#include <stdio.h>
#include <schily/schily.h>
int fixline __PR((char *line, int amt));
main()
{
char line[8192];
int amt;
while ((amt = fgetline(stdin, line, sizeof (line))) >= 0) {
amt = fixline(line, amt);
filewrite(stdout, line, amt);
putchar('\n');
}
return (0);
}
fixline(line, amt)
char *line;
int amt;
{
char *p = line;
if (p[0] != '#')
return (amt);
if (p[1] != ' ')
return (amt);
if (line[amt-1] == '"') {
line[amt] = ' ';
line[amt+1] = '\0';
amt += 1;
}
return (amt);
}
