[Patch] inline.h should not define inline functions with "extern" linkage |
|

I am now building Guile from CVS HEAD with a version of the Sun Forte
C compiler that supports the "inline" keyword.
The "inline" keyword does not imply static linkage, and in fact
inline.h defines the functions `scm_cell' and `scm_double_cell'
explicitly with "extern" linkage.
Therefore, every file that includes inline.h defines a copy of these
two functions, each copy with external linkage. This makes it
impossible to link Guile. (I do not know why this would work with
gcc; it is definitely wrong.)
The patch below fixes it. inline.c defines the functions with
external linkage, and every file including inline.h defines static
inline copies.
The same trick needs to be applied to the external/inline functions
in numbers.h. The patch fixes them as well.
