I kinda noticed it some time ago, but I attributed it to my
imagination back them.  Anyway, the following change is responsible
for the slowdown in benchmarks:

----------------------------
revision 1.199
date: 2003/04/08 00:27:41;  author: karim;  state: Exp;  lines: +38 -36
10- extend GP command line: once flags (-xxx) are processed, remaining
    args are taken to be filenames, read upon startup [ _after_ the gprc
    read statements have been processed ]

+ Cleanup flags
----------------------------

Should be easily fixable.
