Extended Description

Hi all,
As part of the package building stuff, I've encountered a minor problem
with the RTSPEC stuff. In essence, if we disable the compiling of RTSPEC
into the compiler and then try to compile Rand.sac from the stdlib, we
get the following errors:
/tmp/SAC_grBAYc/fun1.c: In function ‘SACwf_Rand__random__i_S__d_S__d_S’:
/tmp/SAC_grBAYc/fun1.c:240: warning: implicit declaration of function ‘SAC_WE_DECL_REG_FLAG’
/tmp/SAC_grBAYc/fun1.c:241: error: expected ‘;’ before ‘SAC_WE_DECL_REG_OBJ’
/tmp/SAC_grBAYc/fun1.c:284: warning: implicit declaration of function ‘SAC_WE_FUN_DEF_END2’
/tmp/SAC_grBAYc/fun1.c:294: error: expected ‘;’ before ‘void’
/tmp/SAC_grBAYc/fun1.c:2098: error: expected declaration or statement at end of input
These macros are defined within runtime/rtspec_h/rtspec.h within a
ifdef/endif of SAC_DO_RTSPEC.
These macros are added to the generated code as part of 
libsac2c/codegen/icm2c_rtspec.c. I would think that the codegen/ICMs
would be omitted from the compiler if RTSPEC is disabled. This seems
not to be case.
