The Sun ONE Studio 8 compiler doesn't appear to like colons outside quotes
in asm() code.

Makefile and compiler output:
cc -g -I/opt/gnome-2.4/include -g -DHAVE_AV_CONFIG_H -I..
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o common.o

I think (example from bswap.h):
 __asm("bswap	%0":
      "=r" (x)     :
can be changed to:
  /* Put all text in quotes in separate statements. */
 __asm("bswap	%0:" );
 __asm("=r (x)     :" );
but I know absolutely no assembly.

In /usr/include/prof.h (only file in that dir with 'asm()'):
#if defined(__i386)
#define MARK(K) {\
		asm("	.data"); \
		asm("	.align 4"); \
		asm("."#K".:"); \
		asm("	.long 0"); \
		asm("	.text"); \
		asm("M."#K":"); \
		asm("	movl	$."#K"., %edx"); \
		asm("	call _mcount"); \
		}
#endif
Note the individual statements and colons within quotes.
