215 # The BIT_FIELD_LIMITS define was written for the C90 (it seems).  I added
216 # another use.  Basically, the problem is that the T3E uses some bit fields
217 # for some st_addr stuff, and then sizeof and address-of fails
218 # I could not use the ams/alpha.o option because the Cray assembler, 'cam'
219 # did not like it.

695 NOTE: The OpenSSL header files have been moved from include/*.h
696 to include/openssl/*.h.  To include OpenSSL header files, now
697 directives of the form
698      #include <openssl/foo.h>
699 should be used instead of #include <foo.h>.
700 These new file locations allow installing the OpenSSL header
701 files in /usr/local/include/openssl/ and should help avoid
702 conflicts with other libraries.
703
704 To compile programs that use the old form <foo.h>,
705 usually an additional compiler option will suffice: E.g., add
706      -I$prefix/include/openssl
707 or
708      -I$pwd/include/openssl
709 to the CFLAGS in the Makefile of the program that you want to compile
710 (and leave all the original -I...'s in place!).
711
712 Please make sure that no old OpenSSL header files are around:
713 The include directory should now be empty except for the openssl
714 subdirectory.
