dnl This has been stripped down a bit by fyodor@insecure.org for

dnl inclusion in Nmap (removed libtool and dynamic library stuff)

dnl Provide the current PCRE version information. Do not use numbers

dnl with leading zeros for the minor version, as they end up in a C
|

dnl macro, and may be treated as octal constants. Stick to single
|

dnl digits for minor numbers less than 10. There are unlikely to be
|
||||
dnl that many releases anyway.

dnl We need to find a compiler for compiling a program to run on the local host
|

dnl while building. It needs to be different from CC when cross-compiling.
|

dnl There is a macro called AC_PROG_CC_FOR_BUILD in the GNU archive for
|
||||
dnl figuring this out automatically. Unfortunately, it does not work with the
|
||||
dnl latest versions of autoconf. So for the moment, we just default to the
|
||||
dnl same values as the "main" compiler. People who are corss-compiling will
|

dnl just have to adjust the Makefile by hand or set these values when they
