* NEWS, README: Update for 4.14.
* i386v-nat.c (i386_insert_aligned_watchpoint): Fix declaration.
(i386_insert_nonaligned_watchpoint): Call aligned instead of
generic watchpoint insertion.

Both commands take a single argument, which is the +expression to evaluate, and must be followed by the commands to +execute, one per line, if the expression is nonzero, the list being +terminated by the word `end'. The `if' command list may include an +`else' word, which causes the following commands to be executed only +if the expression is zero. + +* Fortran source language mode + +GDB now includes partial support for Fortran 77. It will recognize +Fortran programs and can evaluate a subset of Fortran expressions, but +variables and functions may not be handled correctly. GDB will work +with G77, but does not yet know much about symbols emitted by other +Fortran compilers. + +* Better HPUX support + +Most debugging facilities now work on dynamic executables for HPPAs +running hpux9 or later. You can attach to running dynamically linked +processes, but by default the dynamic libraries will be read-only, so +for instance you won't be able to put breakpoints in them.
