[PATCH] Use libtool -export-dynamic flag for portability

[Yaakov (Cygwin/X)]

From: Yaakov Selkowitz <yselkowitz at users.sourceforge.net>

The linker flag required for exporting symbols in executables varies
by platform.  libtool handles this with a single -export-dynamic
flag (not to be confused with the similarly-named ELF linker flag)
which tells it to use the correct platform-specific flag at link time.

 dnl Imake defines SVR4 on SVR4 systems, and many files check for it, so
