cycle-check: needs inline

[Bruno Haible]

Hi Jim,

The cycle-check module uses 'inline', therefore should make sure it's supported
or defined away. Currently it leads to a failure like this, on Solaris 2.5.1
with SunPRO C 5.0:

cc -O -DHAVE_CONFIG_H -I. -I..      -g -c cycle-check.c
"cycle-check.c", line 38: undefined or not a type: inline

Here's a proposed patch.

        * m4/cycle-check.m4 (gl_CYCLE_CHECK): Require AC_C_INLINE.

*** m4/cycle-check.m4   21 Aug 2006 06:11:26 -0000      1.3
