Now passes gcc -Wall -Wextra -Wmissing-declarations -Wwrite-strings on gcc45.
May build with clang now too.
Changes:
- use standard headers
- don't declare own errno, fopen(), getenv(), or malloc()
- declare own functions
- declare void functions void
- avoid implicit int
- use C89
- use some const
- use some static
- fix signed/unsigned mismatches
- call execl() properly
- don't cast return value of malloc
- initialize struct sigaction correctly
- use <ctype.h> functions correctly
- don't index arrays with (signed) char
- don't put function declarations inside function bodies
- patch up two uninitialized variables
- silence some compiler warnings that are not bugs
- remove some unused objects
and:
- add patch comments for preexisting patches
- correct some minor pkglint
As a couple of these things fixed bugs (e.g. the execl calls), bump
PKGREVISION.
