Doh! That was my mistake. :-) It really should be "-x c" not "-x -c".
The latter means something totally different :-)
Sorry, could you try again with my mistake corrected.
Here's an excerpt from the cpp man page on my system:
Specify the source language: C, C++, Objective-C, or
assembly. This has nothing to do with standards
conformance or extensions; it merely selects which base
syntax to expect. If you give none of these options,
cpp will deduce the language from the extension of the
source file: .c, .cc, .m, or .S. Some other common
extensions for C++ and assembly are also recognized. If
cpp does not recognize the extension, it will treat the
file as C; this is the most generic mode.
I thought this -x c feature was portable, where as relying on cpp to
default to C mode for a .h file seems much less so. Perhaps we should
just spit out a .c file instead of a .h file. It wouldn't make much
difference to c2hs as far as I can see.
