Re: problem making swarm-1.4.1 (-O3) under rh6.0

[Rick Riolo]

It doesn't seem to work, nor does a couple of other
variants I tried (the lines are off a bit from yours
because I left the old stuff in there in a #ifdef).
This:

const char* 
skip_typespec (const char *intype)
{
  const char *type = skip_type_qualifiers (intype);  

gives:

/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:
In function `skip_typespec':
/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:37:
warning: `type' might be used uninitialized in this function
/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:37:
warning: `type' might be used uninitialized in this function

This gives two errors:

const char* 
skip_typespec (const char *intype)
{
  const char *type;
  type = skip_type_qualifiers (intype);  

/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:
In function `skip_typespec':
/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:37:
warning: `type' might be used uninitialized in this function
/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:38:
warning: `type' might be used uninitialized in this function

So does the following---gives errors for both lines!!

const char* 
skip_typespec (const char *intype)
{
  const char *type = "x"; 
  type = skip_type_qualifiers (intype);  

Very strange!
