I've found some typos, etc. in chapter 1 ("About This Guide") of the GNAT Reference Manual.
Here they come in order of appearance: #1 This manual contains useful information in writing programs using the GNAT compiler. s/in writing/on writing #2 It includes information on implementation dependent characteristics of GNAT… s/implementation dependent/implementation-dependent #3 GNAT implements Ada 95, Ada 2005 and Ada 2012, and it may also be invoked in Ada 83 compatibility mode. s/Ada 2005 and Ada 2012, and/Ada 2005, and Ada 2012, but #4 By default, GNAT assumes Ada 2012, but you can override with a compiler switch to explicitly specify the language version. s/override/override that #5 Throughout this manual, references to ’Ada’ without a year suffix apply to all the Ada versions of the language. s/’Ada’ without a year suffix/Ada, without a year suffix, or s/’Ada’ without a year suffix/’Ada’ – i.e., without a year suffix – #6 However, since Ada is designed to be used in a wide variety of applications, it also contains a number of system dependent features to be used in interfacing to the external world. s/system dependent/system-dependent s/interfacing to/interfacing with Maybe someone can take the time to fix these.
