3471 ### First figure out CFLAGS (which we use for running the compiler here)
3472 ### and REAL_CFLAGS (which we use for real compilation).
3473 ### The two are the same except on a few systems, where they are made
3474 ### different to work around various lossages.  For example,
3475 ### GCC 2.5 on GNU/Linux needs them to be different because it treats -g
3476 ### as implying static linking.
3477
3478 ### If the CFLAGS env var is specified, we use that value
3479 ### instead of the default.
3480
3481 ### It's not important that this name contain the PID; you can't run
3482 ### two configures in the same directory and have anything work
3483 ### anyway.
