+# AC_PROG_FPC
+#
+# DESCRIPTION
+#
+# Checks for Free Pascal Compiler
+#
+# Sets:
+# PPC : fpc command
+# FPCMAKE : fpcmake command
+#
+# PFLAGS : flags passed to fpc (overwrite default)
+# PFLAGS_BASE : base flags (release + debug)
+# PFLAGS_EXTRA : additional flags (appended to default PFLAGS)
+# PFLAGS_DEBUG : flags used in debug build
+# PFLAGS_RELEASE : flags used in release build
+#
+# Note:
+# all PFLAGS/PFLAGS_XYZ vars are set to $(PFLAGS_XYZ_DEFAULT)
+# if not set by the user, so the Makefile can assign default
+# values to them.
+#
+# FPC_VERSION : fpc version string, e.g. 2.3.1
+# FPC_VERSION_MAJOR : major version (here 2)
+# FPC_VERSION_MINOR : minor version (here 3)
+# FPC_VERSION_RELEASE: release version (here 1)
+#
+# FPC_PLATFORM : platform of the target (linux/darwin/win32/...)
+# FPC_PROCESSOR : processor of the target, (i386/...)
+# FPC_CPLATFORM : platform of the compiler host, (linux/darwin/win32/...)
+# FPC_CPROCESSOR : processor of the compiler host, (i386/...)
+# FPC_TARGET : FPC_PROCESSOR-FPC_PLATFORM (e.g. i386-linux)
+#
+# FPC_PREFIX : prefix of fpc install path, (default: /usr)
+# FPC_BASE_PATH : $FPC_PREFIX/lib/fpc/$FPC_VERSION
+# FPC_UNIT_PATH : $FPC_BASE_PATH/units/$FPC_TARGET
