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

137 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS

1145 - which libraries the lib-src programs will want, and

1148 ### First figure out CFLAGS (which we use for running the compiler here)
1149 ### and REAL_CFLAGS (which we use for real compilation).
1150 ### The two are the same except on a few systems, where they are made
1151 ### different to work around various lossages. For example,
1152 ### GCC 2.5 on GNU/Linux needs them to be different because it treats -g
1153 ### as implying static linking.
1155 ### If the CFLAGS env var is specified, we use that value
1156 ### instead of the default.
1158 ### It's not important that this name contain the PID; you can't run
1159 ### two configures in the same directory and have anything work
1160 ### anyway.
