Headers not precompiling

Headers not precompiling

[Mark Wagner]

According to the documentation
(http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html), creating
a precompiled header is done by invoking GCC on the header the same
way you'd compile a file.  So, the command line

/opt/mingw/i386-mingw32msvc/bin/gcc -fshort-wchar -xc++
-D_MSC_VER=0x0500 -I../../PUBINC -I../NEO/NeoIncludes
-I../NEO/NeoIncludes/ibmpc -I../NEO/NeoIncludes/ibmpc/Alone
-I../NEO/NeoExtras TGEQWin32.h

should produce a a precompiled header called "TGEQWin32.h.gch".  It
doesn't.  Instead, GCC tries to link the header file with the standard
libraries to produce an executable.  Am I doing something stupid here,
or is this a bug?  I'm using GCC 3.4.2 configured as a cross-compiler
to create Windows executables on a Mac computer.

Thanks,
Mark

I think you want -xc++-header, not -xc++.
