egcs-1.0 on mingw32/possibly cygwin32 regression

["Andrew Zabolotny" <bit@freya.etu.ru>]

Hello everybody!

The mingw32 egcs-1.0 port and possibly cygnus-win32 egcs-1.0 (since first
is
heavily based on second) has the following problem:

The program:

---------------
#include <stdio.h>

static __attribute__ ((stdcall)) BlackHole(int a);

void doit()
{
 BlackHole(1);
}

static __attribute__ ((stdcall)) BlackHole(int a)
{
 printf("disappearing function! %d\n", a);
}

int main()
{
 doit();
 return (0);
}
---------------

does not compile correctly with -O3. However, it compiles okay if the
-fkeep-inline-functions or with -fno-inline-functions switch was
specified.
The problem is that the BlackHole function is for some reason marked
as 'inline' but instead of inlining its code the compiler puts a
'call BlackHole@4' anyway, but the actual function code is totally
missing.

This problem is not present with gcc-2.7.2 from cygwin32.

I've did not tracked the problem, but I think it's related to the
ENCODE_SECTION_INFO macro in cygwin32.h (the name of function changes
and compiler detects by name whenever the function is inline??? nonsense)
