Summary: system.h is crufty maybe? Raise the level fo ANSI C89?
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: jay.kr...@cornell.edu
I recently found a compiler that didn't like spaces
after the # in preprocessor directives.
In system.h:
Do any systems lack stddef.h? (it is in ANSI C89)
Do any systems lack #define NULL? (ditto)
Do any systems lack limits.h? (ditto)
Ditto:
string.h? time.h? (ditto)
errno declared in errno.h? (ditto)
SEEK_SET, SEEK_CUR, SEEK_END (ditto)
F_OK, X_OK, W_OK, R_OK
O_RDONLY, O_WRONLY
atof, atol, free, getenv, strstr, abort, offsetof? (ditto)
malloc, calloc, realloc? (ditto)
Posixy systems that gcc can be hosted on: getcwd, getwd, sbrk?
I wonder if all the compability stuff needs to stay.
Along with suggesting a new one -- no spaces after #.
I wonder if the _unlocked stuff is worthwhile.
One should be sure to have reasonably large inputs/outputs, not
just getchar one at a time, for example.
Maybe some of this is for "header-less" environments?
I grant, getting headers for cross build scenarios can be a pain.
But I do need the libraries anyway.
