[sdcc-devel] Cygming configure fails

[Borut R. <bor...@si...>]

Cygming build (cygwin + -mno-nocygwin) fails with the following error:

=== configuring in device/lib/pic16

If I remove --build=`"$SRCDIR/config.guess"` --host=pic16 configure 
options from device/lib/pic16/configure.gnu, everything is OK.

On the other hand, Raphael wrote in device/lib/pic16/configure.ac:

# The (generated) configure script should be called with
#     --build=<your-build-system> --target=pic16
# to force cross-compilation mode; rather use the wrapper
# ./configure.gnu instead of ./configure directly.

Raphael, do you have an idea how to solve the problem? Are 
--build=`"$SRCDIR/config.guess"` and --host=pic16 configure options 
really needed?
