RE: [Gcl-devel] Gcc 3.4 and GCL

[Mike Thomas]

Hi Camm.

| And please accept
| my apologies for being somewhat unresponsive of late -- am in the
| middle of a work burst.

Same on both counts from me.

| 4) Everything else works fine for me.  I get no syntax errors, and
|    need no include reordering.  Can you try to give me a minimum test
|    case, with preprocessed (i.e. through cpp) output?

This was caused by a compiler command line parsing problem triggered by the
trailing '/' in -I../h/.  I've made enquired with the MinGW32 people to see
what the story is.

Making local adjustments here to usage of HDIR in "o/makefile" leads to the
trouble outlined below where page returns a value larger than MAXPAGE.

Haven't time now to look at the calculations by the page macro but
hopefullly tomorrow.

Cheers

Mike Thomas.
