turn down your CFLAGS
if you find out which flag it breaks we could filter it out

Forums thread http://forums.gentoo.org/viewtopic.php?t=74599 shows proftp doesn't 
compile with -mcpu=athlon-mp -O3 -pipe -fomit-frame-pointer -fPIC which led me to 
suspect -fPIC is the likely culprit. 
 
I tested proftpd-1.2.8 with the -fPIC flag and indeed it failed: 
 
gcc -march=pentium4 -O3 -pipe -fomit-frame-pointer -fPIC -Wall -c cap_sys.c -o 
cap_sys.o 
cap_sys.c: In function `capget': 
cap_sys.c:16: can't find a register in class `BREG' while reloading `asm' 
make[1]: *** [cap_sys.o] Error 1 
make[1]: Leaving directory `/var/tmp/portage/proftpd-1.2.8/work/proftpd-1.2.8/lib/libcap' 
make: *** [dirs] Error 2 
 
!!! ERROR: net-ftp/proftpd-1.2.8 failed. 
!!! Function src_compile, Line 69, Exitcode 2 
!!! compile problem 
 
Without the -fPIC flag it compiles ok: 
 
gcc -march=pentium4 -O3 -pipe -fomit-frame-pointer -Wall -c cap_sys.c -o cap_sys.o 
ar rcu libcap.a cap_alloc.o cap_proc.o cap_extint.o cap_flag.o cap_text.o cap_sys.o 
make[1]: Leaving directory `/var/tmp/portage/proftpd-1.2.8/work/proftpd-1.2.8/lib/libcap' 
 
So it looks like this is a duplicate of http://bugs.gentoo.org/show_bug.cgi?id=20798.

For the sake of completeness proftpd compiles ok with all non-athlon flags Veiko used 
except -fPIC: 
 
gcc -march=pentium4 -O3 -pipe -fomit-frame-pointer -frerun-cse-after-loop 
-frerun-loop-opt -fexpensive-optimizations -Wall -c cap_sys.c -o cap_sys.o 
ar rcu libcap.a cap_alloc.o cap_proc.o cap_extint.o cap_flag.o cap_text.o cap_sys.o
