[mp2] [BUG] [PATCH] Build error: HP-UX 11i error w/ fully pathed gcc compiler

[Br...@jci.com]

Using mod_perl 2.0.3.

Error generated is:

      <command line>:3:2: missing '(' after predicate

whenever a compile is attempted.

If Perl was compiled with a fully pathed gcc compiler (/opt/hp-gcc/bin/gcc,
for example), lib/Apache2/Build.PL puts the wrong flags on the compiler
command.  GCC does not understand the "-Ae" compiler flag, so it fails.  I
have looked at the latest development snapshot and they also have this
"problem".

I have seen a previous message that uncommented the #XXX? line in the
source to solve a build problem under gcc on HP-UX.  Not sure if this is
the best solution, (cmp against basename or split may be better, for
example), but it addresses this version of the problem.  One potential
pitfall I could see is if the compiler name ends in "gcc" but is not
actually GCC (minimal risk, but hey :)

Not sure how to generate a test case for this :)
