It appears to be a misfeature of exec*p() or something else, Jordan.
The following is on a 1.1.5.1 system, but apparently identical to the
problem described:

* tweak it:
j@bonnie 148% set path = (/etc/passwd $path)

* now let's look what we've got:
j@bonnie 149% which cc
/usr/bin/cc
j@bonnie 150% cc
cc: No input files specified.

* hmm, fine, what's the problem?  go on:
j@bonnie 151% make
cc -g -O2 -pipe -Wall -I /usr/X11R6/include -c tiff2tdp.c
cc: not found
*** Error code 1

Stop.

* oops, doesn't `make' run something like ``sh -c'' on the commands?
* let's try /bin/sh
j@bonnie 152% sh
$ cc
cc: No input files specified.
$ j@bonnie 153% 

* well ok, seems to work (and i start to remember that our make is
* overly smart and avoids calling a shell if there are no meta chars...)
* -- so try calling cc directly:
j@bonnie 153% cc -g -O2 -pipe -Wall -I /usr/X11R6/include -c tiff2tdp.c
cc: installation problem, cannot exec as: Not a directory
In file included from /usr/include/ctype.h:52, from tiff2tdp.c:39:
/usr/include/runetype.h:94: output pipe has been closed
gcpp: output pipe has been closed

* hmm, it's plain broken.

Never trust an operating system you don't have sources for. ;-)
