My Linux->Win32 cross compilation uses cygwin cross binutils.

i686-cygwin-as --version:
GNU assembler (GNU Binutils) 2.23.1

This assembler was configured for a target of `i686-cygwin'.

However, I have been recently plagued with a snag when creating cross 
compilers (from Ubuntu 32 bits):
i386-win32 / FPC 2.6.3: success
x86_64-win64 / FPC 2.6.3: success
x86_64-linux / FPC 2.6.3: fail
arm-winCE / FPC 2.6.3: success
arm-linux / FPC 2.6.3: fail

i386-win32 / FPC 2.7.1: fail
x86_64-win64 / FPC 2.7.1: fail
x86_64-linux / FPC 2.7.1: fail
arm-winCE / FPC 2.7.1: fail
arm-linux / FPC 2.7.1: fail

The failure message is always similar to:
.../fpc/crossbinutils/bin/x86_64-linux-ld: warning: ./link.res contains 
output sections; did you forget -T?
.../fpc/crossbinutils/bin/x86_64-linux-ld: cannot find -lgcc
.../fpc/crossbinutils/bin/x86_64-linux-ld: cannot find -lc
fpdoc.pp(382,1) Error: Error while linking

I am clueless at this stage.
