%description
T-Rex is a minimalistic regular expression library written in ANSI C, supports
the following POSIX expressions: ?,*,+,^,$,.,[a-b],() plus the perl style
greedy closures {n}.  It can be conditionally compiled to support 8-bits or
16-bits character strings. 

The library is available as 32-bit and 64-bit.

%description devel
This package contains header files and static libraries for use when
building applications which use the T-Rex library.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".

%build
# setup environment for 32-bit and 64-bit builds
export AR="ar -X32_64"

# first build the 64-bit version
export CC="cc -qcpluscmt -q64"

CreateExportList -X64 %{name}.exp lib%{name}.a
${CC} -qmkshrobj lib%{name}.a -o shr.o -bE:%{name}.exp

rm -f %{name}.o lib%{name}.a %{name}.exp

# now build the 32-bit version
export CC="cc -qcpluscmt -q32"
${CC} -c %{name}.c -o %{name}.o
${AR} -rv lib%{name}.a %{name}.o
CreateExportList -X32 %{name}.exp lib%{name}.a
${CC} -qmkshrobj lib%{name}.a -o shr64.o -bE:%{name}.exp

# now create the AIX-style shared library
