14<listitem><para><userinput>LDFLAGS="-static"</userinput>: This is the most
15common way to tell a package that all programs should be statically linked.
16This way the <emphasis>LDFLAGS</emphasis> environment variable is set, but
17only in the subshell that the <filename>configure</filename> script runs
18in. When <userinput>configure</userinput> has done its job, the
19<emphasis>LDFLAGS</emphasis> environment variable won't exist anymore
20and the <filename>Makefile</filename> files contain will contain this
21variable locally.</para></listitem>
22
23<listitem><para><userinput>CPPFLAGS=-Dre_max_failures=re_max_failures2</userinput>: The <emphasis>CPPFLAGS</emphasis> variable is a variable that's read by
24the cpp program (C PreProcessor). The value of this variable tells the
25preprocessor to replace every instance of <emphasis>re_max_failures</emphasis>
26it finds with <emphasis>re_max_failures2</emphasis> before handing the source
27file to the compiler itself for compilation. This package has problems
28linking statically on systems that run an older Glibc version and this
29construction fixes that problem.</para></listitem>
