warnings during compile (msvcrt related)

[Paul Vriens]

Hi,

during a new fresh compilation I saw several warnings:

In file included from ../../include/winnt.h:27,
                 from ../../include/windef.h:234,
                 from crtdll_main.c:28:
../../include/msvcrt/ctype.h:72: warning: conflicting types for built-in function ‘iswalnum’
../../include/msvcrt/ctype.h:73: warning: conflicting types for built-in function ‘iswalpha’

../../include/msvcrt/ctype.h:84: warning: conflicting types for built-in function ‘iswxdigit’
../../include/msvcrt/ctype.h:85: warning: conflicting types for built-in function ‘towlower’

It turns out these errors are generated for some dll's (crtdll and
msvcrtd and their tests). And also for some programs (notepad, regedit,
taskmgr, wordpad).

The common thing is that they all have in their Makefile.in:

EXTRAINCL = -I$(TOPSRCDIR)/include/msvcrt

Is this harmless? Should it (what?) be fixed?

Cheers,

Paul.

There's a configure check to add -fno-builtin for these cases, you
should check why that doesn't work for you.

Well the strange thing is:

gcc -c -I. -I. -I../../include -I../../include -I../../include/msvcrt
-D__WINESRC__  -D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing
-gstabs+ -Wdeclaration-after-statement -Wpointer-arith  -g -O2
-fno-builtin-iswalnum -fno-builtin-iswalpha -fno-builtin-iswcntrl
-fno-builtin-iswdigit -fno-builtin-iswgraph -fno-builtin-iswlower
-fno-builtin-iswprint -fno-builtin-iswpunct -fno-builtin-iswspace
-fno-builtin-iswupper -fno-builtin-iswxdigit -fno-builtin-towlower
-fno-builtin-towupper -o crtdll_main.o crtdll_main.c

Does this mean a gcc bug?

I'm running an up-to-date FC5 install (gcc 4.1.1).

Cheers,

Paul.

It looks like it, yes.
