# String for PACKAGE_NAME macro in the C code and Windows resource files:
#
# windres from GNU binutils can be a bit tricky with command line arguments
# that contain spaces or other funny characters because it will pass them
# to a shell (cmd.exe or /bin/sh). CMake doesn't seem to handle the quoting
# well enough either. Using \x20 to encode the US-ASCII space seems to work:
# it should be compatible with both shell types, it works also with llvm-rc,
# and CMake handles quoting the backslash too.
#
# For simplicity, use this workaround in all cases on Windows as it should
# do no harm with other toolchains. Outside Windows use a regular space as
# then we are compatible with EBCDIC too (if it will ever matter with CMake;
# EBCDIC compatibility is important with the Autotools-based build though).
