configure --prefix=/toolchain --exec-prefix=/toolchain/win32
--with-headers=/src/newlib-1.13.0/newlib/libc/include ....
make all-gcc
dieds when building crtbegin.o due to missing header files.
Looking into the build scripts:
I see that the header files from newlib are copied to
/toolchain/arm-elf/sys-include.
But the compile statement is using
-isystem /toolchain/win32/arm-elf/sys-include (the EXEC_PREFIX path).
So there is a mismatch in using for PREFIX and EXEC_PREFIX for
externally provided header files.
This should be valid for any build using with-headers and specifying a
exec-prefix.
WORKAROUNDs:
ln -s /toolchain/arm-elf/sys-include /toolchain/win32/arm-elf/sys-include
or
don't use --exec-prefix.

Summary: Use of --prefix and --exec-prefix breaks compiler build
with --with-headers
