| <p>GCC supports several types of pragmas, primarily in order to compile |
| code originally written for other compilers. Note that in general |
| we do not recommend the use of pragmas; See <a href="Function-Attributes.html#Function-Attributes">Function Attributes</a>, |
| for further explanation. |
