Precompiling headers using GCC incorrect command line

Attempting to use precompiled headers with GCC on Linux. The header to be compiled intto a GCH target is selected for compilation in the project, but not for linking.

The command-line which is generated by Code::Blocks during the build is:

g++ -Wall -g -Winvalid-pch -include "lib/precompile.hpp" -c /lib/precompile.hpp -o lib/precompile.h.gch

This produces a notification from GCC:

g++: lib/precompile.hpp: linker input file unused because linking not done

... and the precompile.h.gch target is not generated.

It appears that the command-line option "-x c++-header" is not being inserted into the GCC command line to inform the compiler that it is generating a precompiled header rather than an obj.

If you manually add that option before the -c option the compile succeeds, producing the expected .gch file.
