#11 regex compile problem

[Anonymous]

VDK2 uses its own regex library, but vdkbuilder2 uses
vdk2 and also uses the system regex.h and regex calls.

System regex.h and regex calls are not the same on
all the OSs and are not portable. As an example
vdkbuilder does not compile on HP-UX 11 because of
the differences in regex.h between HP-UX 11 abd GNU
libc.

May be it's better to include regex.h and regex.c
with vdk-builder and not use the system regex.h.

Even better, the vdk regex library could be enhanced
to support vdkbuilder needs and thus remove the
dependency between vdkbuilder and the system regex.
