* Library changes We fixed problems caused by using too many file descriptors
for reading symbols from object files and libraries. This was
especially a problem for programs that used many (~100) shared
libraries.
* Configuration The `step' command now only enters a subroutine if there is line number
information for the subroutine. Otherwise it acts like the `next'
command. Previously, `step' would enter subroutines if there was
any debugging information about the routine. This avoids problems
when using `cc -g1' on MIPS machines.
* New hosts supported * Internal improvements
GDB's internal interfaces have been improved to make it easier to support
debugging of multiple languages in the future.
