Package: gcc-4.4
Version: 4.4.4-11
Severity: important
gcc in Squeeze prefers header files from the current directory over
those in system paths for #include <foo>:
sascha.si...@twin:/tmp/sascha_silbe/tmpbox.4Pe8smERA3$ cat > test.c
#include <stdio.h>
#include <locale.h>
int main(int argc, char **argv)
{
printf("%d\n", LC_MESSAGES);
return 0;
}
sascha.si...@twin:/tmp/sascha_silbe/tmpbox.4Pe8smERA3$ gcc -Wall -o test test.c
&& ./test
5
sascha.si...@twin:/tmp/sascha_silbe/tmpbox.4Pe8smERA3$ touch locale.h
sascha.si...@twin:/tmp/sascha_silbe/tmpbox.4Pe8smERA3$ gcc -Wall -o test test.c
&& ./test
test.c: In function 'main':
test.c:6: error: 'LC_MESSAGES' undeclared (first use in this function)
test.c:6: error: (Each undeclared identifier is reported only once
test.c:6: error: for each function it appears in.)

I would have expected this for #include "locale.h", but not #include <locale.h>.
This breaks at least ion3 (not available in Debian anymore, so I have
to build it locally).
While the C standard seems to avoid defining almost any semantics for
#include <> vs. #include "", the latter is supposed to search in the
"current directory" first, and if nothing is found it should continue
like for #include <>. [1] This rule (and the differentation between
#include "" and #include <>) only makes sense if #include <>
does NOT search the "current directory" first.
For this reason I believe that having the current directory searched
first for #include <> is not only troublesome in practice, but actually
a violation of the standard (but cannot verify the latter because I
don't own a copy of the standard).
