133 ### based on the machine portion of the configuration name, and an s-
134 ### file based on the operating system portion. However, it turns out
135 ### that each m/*.h file is pretty manufacturer-specific - for

1159 ### and REAL_CFLAGS (which we use for real compilation).
1160 ### The two are the same except on a few systems, where they are made
1161 ### different to work around various lossages. For example,
1162 ### GCC 2.5 on GNU/Linux needs them to be different because it treats -g
1163 ### as implying static linking.
1165 ### If the CFLAGS env var is specified, we use that value
1166 ### instead of the default.
1168 ### It's not important that this name contain the PID; you can't run
1169 ### two configures in the same directory and have anything work
1170 ### anyway.
