Commit 8c893aa3cd5 removed quotes that were required to detect
inline asm:
check_insn armv5te qadd r0, r0, r0
.../test.c:1:34: error: expected string literal in 'asm'
void foo(void){ __asm__ volatile(qadd r0, r0, r0); }
The correct code is:
void foo(void){ __asm__ volatile("qadd r0, r0, r0"); }

External library support:
 | 
						|
 | 
						|
  Using any of the following switches will allow Libav to link to the
 | 
						|
  corresponding external library. All the components depending on that library
 | 
						|
  will become enabled, if all their other dependencies are met and they are not
 | 
						|
  explicitly disabled. E.g. --enable-libwavpack will enable linking to
 | 
						|
  libwavpack and allow the libwavpack encoder to be built, unless it is
 | 
						|
  specifically disabled with --disable-encoder=libwavpack.
 | 
						|
 | 
						|
  Note that only the system libraries are auto-detected. All the other external
 | 
						|
  libraries must be explicitly enabled.
 | 
						|
 | 
						|
  Also note that the following help text describes the purpose of the libraries
 | 
						|
  themselves, not all their features will necessarily be usable by Libav.
