maybe; I would guess this is a shell feature?
Anyway, I can browse google for it; I never needed that before.

OK, I will try it on the next weekend, when I have enough time.
On a 50 MHZ R4k it takes a few hours for one run.

I will try that, using e.g. /tmp, but it will take time.
Anyway, I'll come back to you when I need further help or have further input.

BTW, /usr/include/limits.h says:

/*
 * ARG_MAX
 * CHILD_MAX
 * OPEN_MAX
 * STREAM_MAX
 *
 * PATH_MAX
 * NAME_MAX
 * LINK_MAX
 * - are available only thru sysconf/pathconf
 */

...

#ifndef PATH_MAX
#define PATH_MAX        1024            /* max # of characters in a path name */
#endif
#ifndef ARG_MAX
#define ARG_MAX         5120
#endif



the limits man page says:

#define ARG_MAX     10240      /* max length of arguments to exec */

(it seems the man page is wrong by a factor of 2 here; or maybe the 5120
above is only the last resort value. Is ARG_MAX of relevance to the gcc
problem? Is that what you are looking for?
