fix invalid implicit pointer conversion in gnulib-compat functions

2012-09-07T03:27:55+00:00

use restrict everywhere it's required by c99 and/or posix 2008

2012-09-07T02:44:55+00:00

to deal with the fact that the public headers may be used with pre-c99
compilers, __restrict is used in place of restrict, and defined
appropriately for any supported compiler. we also avoid the form
[restrict] since older versions of gcc rejected it due to a bug in the
original c99 standard, and instead use the form *restrict.

implement "low hanging fruit" from C11

2012-08-26T03:15:13+00:00

based on Gregor's patch sent to the list. includes:
- stdalign.h
- removing gets in C11 mode
- adding aligned_alloc and adjusting other functions to use it
- adding 'x' flag to fopen for exclusive mode

add bsd fgetln function

2012-08-11T22:10:38+00:00

optimized to avoid allocation and return lines directly out of the
stream buffer whenever possible.

minor but worthwhile optimization in printf: avoid expensive strspn

2012-08-11T03:39:32+00:00

the strspn call was made for every format specifier and end-of-string,
even though the expected return value was 1-2 for normal usage.
replace with simple loop.

trivial optimization to printf: avoid wasted call frame

2012-08-11T02:18:49+00:00

amusingly, this cuts more than 10% off the run time of printf("a"); on
the machine i tested it on.

sadly the same optimization is not possible for snprintf without
duplicating all the pseudo-FILE setup code, which is not worth it.

putw is supposed to return 0 (not the value written) on success

2012-07-04T16:21:22+00:00

this is not a standard but it's the traditional behavior and it's more
useful because the caller can reliably detect errors.

make sure getw/putw agree with prototypes by defining _GNU_SOURCE
