The point of the code, according to its comment,
is to workaround an issue with the debug info output by the
native Irix compiler. You wouldn't want a cross-Irix,
Windows-hosted gdb looking for '\' or a drive prefix in order
to decide whether to apply the workaround. In other words,
we _always_ want to check for literal '/' here:
if (*comp_dir != NULL)
{
/* Irix 6.2 native cc prepends <machine>.: to the compilation
directory, get rid of it. */
char *cp = strchr (*comp_dir, ':');
if (cp && cp != *comp_dir && cp[-1] == '.' && cp[1] == '/')
*comp_dir = cp + 1;
}
