strtod: fix clash with strtold
Problem reported for RHEL 5 by Jesse Caldwell (Bug#34817).
* lib/strtod.c (compute_minus_zero, minus_zero):
Simplify by remving the macro / external variable,
and having just a function. User changed. This avoids
the need for an external variable that might clash.

This can be useful for system calls like sendfile on GNU/Linux, which do not handle more than MAX_RW_COUNT bytes correctly. The Linux kernel MAX_RW_COUNT is at least INT_MAX >> 20 << 20, where the 20 comes from the Hexagon port with 1 MiB pages; use that as an approximation, as the exact value may not be available to us. Using this also works around a serious Linux bug before 2.6.16; see <https://bugzilla.redhat.com/show_bug.cgi?id=612839>. Using this also works around a Tru64 5.1 bug, where attempting to read INT_MAX bytes fails with errno == EINVAL. See <https://lists.gnu.org/r/bug-gnu-utils/2002-04/msg00010.html>. Using this is likely to work around similar bugs in other operating systems. */ enum { SYS_BUFSIZE_MAX = INT_MAX >> 20 << 20 }; #endif
