This is a useful book for those who need in-depth information on GCC, but needs more effort in both writing and editing. There are numerous copy-paste-itis errors, which shows that it was not properly proof-read. It also has passages in various chapters which are nearly duplicates of each other, e.g., two "Multiple Source Files to Executable" passages (pages 70 & 106), and five on "Creating a Shared Library" (73, 110, 132, 144, 165). Admittedly some of the details vary from language to language, but there's no explanation of what these differences are; the passages are merely repeated with minor changes.



There are larger but similar problems with the organization of the book. For example, I would have greatly preferred a logically-organized listing of command-line options to a merely alphabetical order. A reader who wants an alphabetical organization can already get it from the manual. This arrangement also leads to problems with the exposition, e.g., the definition of -MQ assumes the definition of -MT, which it precedes. There are other problems with the order of exposition; for example, there's a two and a half page sample of RTL code on 367-9, which is incomprehensible before the explanation of RTL on pp. 387-417, and badly in need of more detailed exposition even afterwards.
