Most 61of these are not GCC bugs per se—if they were, we would fix them. 62But the result for a user may be like the result of a bug. 63 64 <p>Some of these problems are due to bugs in other software, some are 65missing features that are too much work to add, and some are places 66where people's opinions differ as to what is best. 67 68<ul class="menu"> 69<li><a accesskey="1" href="Actual-Bugs.html#Actual-Bugs">Actual Bugs</a>: Bugs we will fix later. 70<li><a accesskey="2" href="Cross_002dCompiler-Problems.html#Cross_002dCompiler-Problems">Cross-Compiler Problems</a>: Common problems of cross compiling with GCC. 71<li><a accesskey="3" href="Interoperation.html#Interoperation">Interoperation</a>: Problems using GCC with other compilers, 72 and with certain linkers, assemblers and debuggers. 73<li><a accesskey="4" href="Incompatibilities.html#Incompatibilities">Incompatibilities</a>: GCC is incompatible with traditional C. 74<li><a accesskey="5" href="Fixed-Headers.html#Fixed-Headers">Fixed Headers</a>: GCC uses corrected versions of system header files. 75 This is necessary, but doesn't always work smoothly. 76<li><a accesskey="6" href="Standard-Libraries.html#Standard-Libraries">Standard Libraries</a>: GCC uses the system C library, which might not be 77 compliant with the ISO C standard. 78<li><a accesskey="7" href="Disappointments.html#Disappointments">Disappointments</a>: Regrettable things we can't change, but not quite bugs. 79<li><a accesskey="8" href="C_002b_002b-Misunderstandings.html#C_002b_002b-Misunderstandings">C++ Misunderstandings</a>: Common misunderstandings with GNU C++. 80<li><a accesskey="9" href="Non_002dbugs.html#Non_002dbugs">Non-bugs</a>: Things we think are right, but some others disagree. 81<li><a href="Warnings-and-Errors.html#Warnings-and-Errors">Warnings and Errors</a>: Which problems in your code get warnings, 82 and which get errors. 83</ul> 84 85 </body></html> 86 87
