include dirs are prepared as in gcc
- for each duplicate path keep just the first one
- remove each include_path that exists in sysinclude_paths
include_next streamlined by introducing inc_path_index
in the BufferedFile
gcc-3.4.6 don't give such error by default
example file1
char __version_303_xxxxxxxx;
void func1() {}
example file2
char __version_303_xxxxxxxx;
void func2() {}
int main() { return 0; }
This version looks rigth. Comparing to the original
algorithm:
1) Loop breaking. We remember a start point after wich
we can try next path. Do not search include stack after
this.
2) But compare next file patch with the start point.
Skip if it the same. Remove "./" before comparing.
PS: a problems with compaling a coreutils-8.24.51-8802e
remain. There are errors messages like:
src/chgrp
src/chown-core.c:42: multiple definition of `make_timespec'
src/chgrp.c:42: first defined here
A problem is in the lib/config.h
#define _GL_INLINE_ extern inline // gcc
#define _GL_INLINE_ inline // tcc
A long description from the lib/config.h
* suppress extern inline with HP-UX cc, as it appears to be broken
* suppress extern inline with Sun C in standards-conformance mode
* suppress extern inline on configurations that mistakenly use
'static inline' to implement functions or macros in standard
C headers like <ctype.h>.
GCC and Clang are excluded from this list. Why not tcc?
don't give an error and simply ingnore directive
if we detect a loop of the #include_next.
With this aproach coreutils-8.24.51-8802e
compiles, but with errors:
lib/libcoreutils.a: error: 'xnmalloc' defined twice
lib/libcoreutils.a: error: 'xnrealloc' defined twice
don't panic with
error: '.' expected
if there is only two '.' chars. Return tok='.' in such case.
An asm code to test:
jz do_move0 # .. then we have a normal low
# .. or else we have a high
The call to build_got can cause symtab_section->data to be reallocated
(build_got -> add_elf_sym -> put_elf_sym -> section_ptr_add ->
section_realloc -> tcc_realloc). This is not obvious on a cursory
inspection, but fortunately Valgrind spotted it immediately.
Are there other, similar bugs that Valgrind did not detect?
don't crash
a test program:
================
typedef struct X { int len; } X;
#define init(s,len) s.len = len;
int main(void) {
X myX;
init(myX,10);
return 0;
}
================
After a patch:
error: field name expected
a test program:
========
typedef struct X { int len; } X;

Error message before a patch:
error: ';' expected (got "(null)")
After a patch:

* Documentation is now in "docs".
* Source code is now in "src".
* Misc. fixes here and there so that everything still works.
I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...
