[Sdcc-user] SDCC2.2.0a compiling failed under cygwin

[Dai Y. <yu...@mi...>]

I downloaded SDCC2.2.0a source and trie to compile it.
make > make.ouput  2>&1
Some lines of make.ouput look like those:
...
cpplib.o: In function `my_strerror':
/tmp/sdcc/support/cpp/cpplib.c:7487: undefined reference to `sys_nerr'
/tmp/sdcc/support/cpp/cpplib.c:7487: undefined reference to
`sys_errlist'
collect2: ld returned 1 exit status
make[1]: *** [../../bin/sdcpp] Error 1
make[1]: Leaving directory `/tmp/sdcc/support/cpp'

It seems that there's an error in the source file 'cpplib.c'. I cann't
find the place where the external variable `sys_nerr' cann't is defined.
Any person can help me?

My system is: cygwin1.1.0 on a windows2000. Cygwin is installed in drive
C: .
