Hello,
Just installed 2.1.0-950726-SNAP, really like the
improvement in the install process since 2.0! The only
problem I had was the need for the '-alldirs' directive
on the host holding the NFS source, the 2.0 script allowed
me to mount '/usr' then provide a path from there.
I attempted to port X11R6/XFree86-3.1 directly
from my source tree (used for various OS's), ran into two
problems for which I found no patches in ports-CURRENT:
1: the source expects to find /usr/include/machine/ioctl_pc.h
which isn't there, I copied the one from 1.1.5.1 and this was
resolved. WHat is the proper fix?
2: compiling the SVGA server causes:
.....

rm -f vgafillarcC.o
gcc -c -m486 -O2 -I. -I../../../../../../programs/Xserver/hw/xfree86/common -I

vgafillarcC.c:105: this is a previous declaration
vgafillarcC.c:119: duplicate label `label1'
*** Error code 1
Stop.
.....
I distilled the problem down to the following sample. It compiles
without problem under 1.1.5.1/gcc-2.4.5 but FAILs as follows under
2.1.0/gcc-2.6.3:
#define XXX() \
{ \
__label__ label1; \
{ \
label1: \
} \
x += 1; \
}
foo()
{
int x;
XXX();
XXX();
}
% gcc label.c
label.c: In function `foo':
label.c:15: duplicate label declaration `label1'
label.c:14: this is a previous declaration
label.c:15: duplicate label `label1'
the inner brackets evidently no longer localize the scope of
"label1". Should the X11 source be fixed or is this a bug in
gcc-2.6.3?
