<h1>8 Compile-time and Link-time Problems</h1>

<p>Being of a Unix origin, GCC has a somewhat different flavor of
command-line syntax and its peculiar compilation and link algorithms.  It
also has a plethora of optional switches, some of them obscure or
semi-documented.  These are known to confuse users, especially those who
had previous experience with DOS-based C compilers.

<p>This chapter explains how to solve some of those problems which tend to
appear when compiling and linking your programs.
