I didn't come up with a better fix by that time.
for one case it includes the system's, for another tinycc's - simply including
stdint.h unconditionally breaks because of this:
------------ dlltest with PIC ------------
Hello World
------------ cross-test ------------
. i386
In file included from tcctest.c:56:
In file included from ../tcclib.h:10:
../include/stddef.h:8: error: incompatible redefinition of 'intptr_t'
That old define was there for uintptr_t, which is what stdint.h is for,
stddef.h would be the wrong place.
An alternative solution (and, in my opinion, a more correct fix) would be to
remove that definition from stddef (see
https://en.cppreference.com/w/c/header/stddef):
--- a/include/stddef.h
+++ b/include/stddef.h
@@ -2,11 +2,8 @@
#define _STDDEF_H
typedef __SIZE_TYPE__ size_t;
typedef __PTRDIFF_TYPE__ ssize_t;
typedef __WCHAR_TYPE__ wchar_t;
typedef __PTRDIFF_TYPE__ ptrdiff_t;
-typedef __PTRDIFF_TYPE__ intptr_t;
-typedef __SIZE_TYPE__ uintptr_t;
which works fine for compiling tcc, but when modified to unconditionally
include stdint.h (otherwise it errors out because of missing typedef):
------------ cross-test ------------
. i386
. i386-win32
tcctest.c:1: error: include file 'stdint.h' not found
which explains why it included tcc's own stddef.h - system includes are not
searched?
should be fixable by modifying tests/Makefile
My suggestion would be to revert that commit, to remove (u)intptr_t from
stddef.h, and to fix the makefile.
