2019-10-17define LONG_MAX via arch alltypes.h, strip down bits/limits.hRich Felker-7/+0
LLONG_MAX is uniform for all archs we support and plenty of header and code level logic assumes it is, so it does not make sense for limits.h bits mechanism to pretend it's variable. LONG_BIT can be defined in terms of LONG_MAX; there's no reason to put it in bits. by moving LONG_MAX definition to __LONG_MAX in alltypes.h and moving LLONG_MAX out of bits, there are now no plain-C limits that are defined in the bits header, so the bits header only needs to be included in the POSIX or extended profiles. this allows the feature test macro logic to be removed from the bits header, facilitating a long-term goal of getting such logic out of bits. having __LONG_MAX in alltypes.h will allow further generalization of headers. archs without a constant PAGESIZE no longer need bits/limits.h at all.
2018-03-10reverse definition dependency between PAGESIZE and PAGE_SIZERich Felker-1/+1
PAGESIZE is actually the version defined in POSIX base, with PAGE_SIZE being in the XSI option. use PAGESIZE as the underlying definition to facilitate making exposure of PAGE_SIZE conditional.
2012-05-22fix missing _BSD_SOURCE support in bits/*.hRich Felker-1/+1
this is actually rather ugly, and would get even uglier if we ever want to support further feature test macros. at some point i may factor the bits headers into separate files for C base, POSIX base, and nonstandard extensions (the only distinctions that seem to matter now) and then the logic for which to include can go in the main header rather than being duplicated for each arch. the downside of this is that it would result in more files having to be opened during compilation, so as long as the ugliness does not grow, i'm inclined to leave it alone for now.
