Summary: build fails because of gsl/gsl_math.h inlines

Initial Comment:


When compiling bogofilter 0.15.7 or 0.15.8 under
FreeBSD 4.7 (gcc 2.95.4, no GSL installed) or under
Solaris7 (gcc 3.2, no GSL installed), the bogofilter
build fails, and in both cases for the same reason.

Under FreebSD:

This seems to be a problem related to the use of 
inline code in gsl/gsl_math.h.

configure checks for inline support, adds "#define
HAVE_INLINE 1" to src/config.h, and then the build fails.

If I remove this define from config.h, everything
compiles ok.


A simplified example based on gsl/gsl_math.h:
-----8<-----
#define GSL_MAX(a,b) ((a) > (b) ? (a) : (b))

#if HAVE_INLINE
extern inline double GSL_MAX_DBL (double a, double b);

extern inline double
GSL_MAX_DBL (double a, double b)
{
  return GSL_MAX (a, b);
}
#else
#define GSL_MAX_DBL(a,b)   GSL_MAX(a,b)
#endif /* HAVE_INLINE */

int main()
{
   double a,b;
   double c = GSL_MAX_DBL(a,b);
   return 0;
}
-----8<-----

Compiling with inline:

freebsd$ gcc -DHAVE_INLINE foo.c -o foo
/tmp/ccjP0chh.o: In function `main':
/tmp/ccjP0chh.o(.text+0x19): undefined reference to
`GSL_MAX_DBL'

solaris$ gcc -DHAVE_INLINE foo.c -o foo
Undefined                       first referenced
 symbol                             in file
GSL_MAX_DBL                         /tmp/ccP54RB7.o
ld: fatal: Symbol referencing errors. No output written
to foo

Compiling without inline works fine in both cases.
