746 | ### First figure out CFLAGS (which we use for running the compiler here) | |
747 | ### and REAL_CFLAGS (which we use for real compilation). | |
748 | ### The two are the same except on a few systems, where they are made | |
749 | ### different to work around various lossages. For example, | |
750 | ### GCC 2.5 on GNU/Linux needs them to be different because it treats -g | |
751 | ### as implying static linking. | |
752 | ||
753 | ### If the CFLAGS env var is specified, we use that value | |
754 | ### instead of the default. | |
755 | ||
756 | ### It's not important that this name contain the PID; you can't run | |
757 | ### two configures in the same directory and have anything work | |
758 | ### anyway. | |
