[avr-gcc-list] Problem building avr-gcc on MinGW

[Ebert, Rolf]

I think I am almost through building an AVR cross compiler on MinGW.  There
seems to be only a little problem left.  When linking collect2.exe I get
unresolved symbols kill, pipe, and fork:

gcc   -g -O2 -DIN_GCC -DCROSS_COMPILE  -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic
-Wno-long-long   -DHAVE_CONFIG_H  -o Tcollect2.exe \
        collect2.o tlink.o intl.o version.o   ../libiberty/libiberty.a 
collect2.o(.text+0x2e3): In function `handler':
d:/data/Development/gcc-cvs/avr/gcc/gcc/../../../gcc-branch_3.3-2003-01-28/g
cc/collect2.c:447: undefined reference to `kill'
collect2.o(.text+0x3ab4): In function `scan_prog_file':
d:/data/Development/gcc-cvs/avr/gcc/gcc/../../../gcc-branch_3.3-2003-01-28/g
cc/collect2.c:2092: undefined reference to `pipe'
collect2.o(.text+0x3b52):d:/data/Development/gcc-cvs/avr/gcc/gcc/../../../gc
c-branch_3.3-2003-01-28/gcc/collect2.c:2115: undefined reference to `fork'
make[1]: *** [collect2.exe] Error 1

I do not have the log from building the native compiler, so I cannot tell
where the native version finds these symbols.  Probably it is just missing a
library here (but which one? this ought to be in libc, doesn't it?)

Anyway, the programs built up the here seem to work correctly, even the Ada
compiler :-)  If I invoke the compiler at the build location, I get the
following output:

I use my own copy (via CVS) of the gcc sources, pulled from the gcc-3.3
branch on January 28.  Are there any pending patches regarding the AVR port?
