Subject: [Bug c/30439] New: Intended Behaviour? #include <signal.h> searches for signal.h in local directory
Date: Thu, 11 Jan 2007 17:27:00 -0000 [thread overview]
Message-ID: <bug-30439-13903@http.gcc.gnu.org/bugzilla/> (raw)
Problem:
#include<signal.h> does not include /usr/include/signal.h (the library header)
if ./signal.h exists.
Expected Behavior:
If a file ./signal.h exists, #include<signal.h> includes /usr/include/signal.h
and #include "signal.h" includes ./signal.h
As far as I know, ANSI C states that #include<signal.h> includes only library
files and not user files (e.g. in the local directory).
Steps to Reproduce:
try to compile attached testcase
Additional Information:
gcc -v
Using built-in specs.
