+ /* PR ld/19260: 32-bit Solaris has very inelegant handling of the 255
+ file descriptor limit. The problem is that setrlimit(2) can raise
+ RLIMIT_NOFILE to a value that is not supported by libc, resulting
+ in "Too many open files" errors. This can happen here even though
+ max_open_files is set to rlim.rlim_cur / 8. For example, if
+ a parent process has set rlim.rlim_cur to 65536, then max_open_files
+ will be computed as 8192.
+
+ This check essentially reverts to the behavior from binutils 2.23.1
+ for 32-bit Solaris only. (It is hoped that the 32-bit libc
+ limitation will be removed soon). 64-bit Solaris libc does not have
+ this limitation. */
