aeb87a49a7 cosmetics: typo fix

7ad6469eae Convert asm keyword into __asm__.
Neither the asm() nor the __asm__() keyword is not part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 synta.

6683a37f89 Invert logic for the single-pass in swScale() functions.
Instead of having a firstTime variable defaulting to 1, have a
warnedAlready defaulting to 0. While this should make no difference in
code speed at runtime, it allows to aggregate the four bytes of that
variable with clip_table in .bss section, rather than issuing a .data
section just for that.

As it is, libswscale require no .data section but .data.rel.ro (that
can be mitigated by prelinking), so the change might actually save one
page of memory at runtime (per process).

4bb9adcff1 10000l PIX_FMT_MONOWHITE check was really a || 1.
Thats what happens when one does not do the full set of tests before each commit
and just quickly goes over the diff thinking, "hey its a trivial change".
