1107 ### First figure out CFLAGS (which we use for running the compiler here)
1108 ### and REAL_CFLAGS (which we use for real compilation).
1109 ### The two are the same except on a few systems, where they are made
1110 ### different to work around various lossages. For example,
1111 ### GCC 2.5 on Lignux needs them to be different because it treats -g
1112 ### as implying static linking.
1113
1114 ### If the CFLAGS env var is specified, we use that value
1115 ### instead of the default.
1116
1117 ### It's not important that this name contain the PID; you can't run
1118 ### two configures in the same directory and have anything work
1119 ### anyway.
