testcase
Testcase:
if ./signal.h exists, it fails to compile, since sig_atomic_t is not defined.
If ./signal.h does not exist it works fine, since /usr/include/signal.h is
included.

Your are correct, I have C_INCLUDE_PATH set (sorry I forgot to mention it). I
did not think it important, but it is. If C_INCLUDE_PATH ends with a colon,
compilation fails. Removing the colon is not a problem in general, but in my
special case it is happening because it is set up in my .bashrc like so:
export C_INCLUDE_PATH=/home/cbs/local/include:$C_INCLUDE_PATH, so I do not see
a way of properly doing it save for checking if C_INCLUDE_PATH is empty before
adding to it.

"a:" means have a and the current directory.
So this is not a bug, C_INCLUDE_PATH acts just like PATH in that an empty
argument after the colon means the current directory.

There are a bunches of way of checking if C_INCLUDE_PATH is set, like
$(?C_INCLUDE_PATH) I think will tell you if it is set or not. This is not the
right forum to ask about shell programming really.
