Hi everyone !

With CPUTYPE=p3 in '/etc/make.conf', compilation breaks as such:
[ ... ]
===> usr.bin/uname
===> usr.bin/undo
cc -O -pipe -march=pentium3 -march=pentium3
-I/usr/src/usr.bin/undo/../../sys
-Wsystem-headers -Werror -Wall -W -Wno-unused-parameter
-Wstrict-prototypes -Wmi
ssing-prototypes -Wpointer-arith -Wreturn-type -Wcast-qual
-Wwrite-strings -Wswi
tch -Wshadow -Wcast-align -Wunused-parameter -Wchar-subscripts -Winline
-Wnested -externs -Wredundant-decls -c /usr/src/usr.bin/undo/undo.c
cc1: warnings being treated as errors
/usr/src/usr.bin/undo/undo.c: In function 'output_history':
/usr/src/usr.bin/undo/undo.c:489: warning: 'hen.unused' may be used
uninitialize
d in this function
  • Error code 1
Stop in /usr/src/usr.bin/undo.
  • Error code 1
Stop in /usr/src/usr.bin.
  • Error code 1

Sticking CPUTYPE=i686 instead of CPUTYPE=p3 in '/etc/make.conf' breaks
compilation with the same double ( -march=* ):
===> usr.bin/undo
cc -O -pipe -march=pentiumpro -march=pentiumpro
-I/usr/src/usr.bin/undo/../../sy

What is the solution to this strangness?

Regards,

Robert.

It's some gcc stupidity (generating different warnings if -march is
tweaked). I guess we can't do much about that problem.

So I've taken out -Werror for now. Please update and try again.
