 844 ### First figure out CFLAGS (which we use for running the compiler here)
 845 ### and REAL_CFLAGS (which we use for real compilation).
 846 ### The two are the same except on a few systems, where they are made
 847 ### different to work around various lossages.  For example,
 848 ### GCC 2.5 on GNU/Linux needs them to be different because it treats -g
 849 ### as implying static linking.
 850
 851 ### If the CFLAGS env var is specified, we use that value
 852 ### instead of the default.
 853
 854 ### It's not important that this name contain the PID; you can't run
 855 ### two configures in the same directory and have anything work
 856 ### anyway.
