Re: Inline machinery

[Greg Troxel]

  The `inline.h' machinery is confusing for some compilers (e.g.,
  DEC/Compaq/HP CC).  The issue is the following: when an inline keyword
  is supported and a non-GCC compiler is used, the header looks like this:

    extern SCM scm_cell (...);

    static inline
    scm_cell (...)
    { ... }

Perhaps I'm confused too, but the compiler's complaint seems correct.

This points out that some time I'm bored I should try to build with pcc,
which is derived from an old C compiler, and is now included in NetBSD.
Using a second compiler has apparently resulted in many failures to
conform to C99 being fixed.

The patch seems ok, but I also wonder if the problem couldn't be solved
leaving the declarations by defining macros that expand properly to
extern/not and using them as



    INLINE_SCOPE_DECLARATION_KEYWORD SCM scm_cell (...);

    INLINE_SCOPE_DEFINITION_KEYWORD inline
    scm_cell (...)
    { ... }


So we could have either 

   static/static

or
   extern/[emtpy]
