* CMakeLists.txt: TARGET_COMPILE_DEFINITIONS does not correctly handle
  values with spaces for MinGW windres, which invokes cc1.exe as its
  preprocessor.  Defines like LONG_NAME="Apache HTTP Server htdbm
  program" get split on spaces, causing "fatal error: HTTP\: No such
  file or directory" and similar errors.  LONG_NAME, BIN_NAME,
  APP_FILE, and ICON_FILE are only used in build/win32/httpd.rc, so
  generate per-target wrapper .rc files with these defines baked in as
  #define directives, then #include the real httpd.rc.  This avoids
  command-line quoting entirely.
  Also fix TARGET_COMPILE_OPTIONS in the standard_support FOREACH loop
  which incorrectly referenced ${mod_name} from the outer modules loop
  instead of ${pgm}.

Claude's explanation of the root cause:

  Root cause: Commit ed4ffd0 replaced the DEFINE_WITH_BLANKS() macro with
  TARGET_COMPILE_DEFINITIONS(), which correctly handles spaces for the C compiler but NOT for MinGW's
  windres.exe. The resource compiler invokes cc1.exe as its preprocessor, and -DLONG_NAME="Apache HTTP
  Server htdbm program" gets split on spaces — each word after Apache gets treated as an input file,
  causing the fatal error: HTTP\: No such file or directory errors.

* CMakeLists.txt (GENERATE_RC_FILE): For MinGW, compile the .rc file
  via ADD_CUSTOM_COMMAND with only the include paths actually needed
  by httpd.rc (just ${CMAKE_SOURCE_DIR}/include for ap_release.h).
  This avoids passing all target include directories to windres, which
  cannot handle -I paths containing spaces such as the default
  CMAKE_INSTALL_PREFIX of "C:/Program Files (x86)/HTTPD/include".

* CMakeLists.txt: ap_config.h includes ap_config_auto.h when
  __MINGW32__ is defined, but autoconf is not used in the CMake
  build so the file does not exist.  Generate an empty one in the
  build directory to satisfy the include.

* modules/arch/win32/mod_win32.c (set_interpreter_source): Change
  third parameter from char * to const char * to match the
  AP_INIT_TAKE1 function signature.
