dnl ** Versions
dnl ** --------
dnl ** 1.0 - Created
dnl **
dnl ** 1.1 - Added stuff to enable unix -> win32
dnl ** cross compilation.

dnl ** 1.x - A few fixes (by the UltraStar Deluxe Team)

AC_ARG_VAR(PFLAGS_RELEASE, [Free Pascal Compiler release flags @<:@-O2 -Xs -vew@:>@])
AC_ARG_VAR(PFLAGS_EXTRA, [Free Pascal Compiler additional flags])
dnl set DEBUG/RELEASE flags to default-values if unset
dnl - Do not use -dDEBUG because this will enable range-checks that will fail with USDX.
dnl - Disable -Xs which is defined in fpc.cfg (TODO: is this necessary?).
dnl - For FPC we have to use DEBUG_MODE instead of DEBUG to enable the apps debug-mode
dnl because DEBUG enables some additional compiler-flags in fpc.cfg too
PFLAGS_DEBUG=${PFLAGS_DEBUG-"-gl -Xs- -vew -dDEBUG_MODE"}
dnl -dRELEASE works too but we define our own settings
