Re: [Gcl-devel] GCL on mingw

Hi Vadim!  And thanks!

OK, so now I believe this build uses the sbrk emulation routine found
in unexnt.c.  Please repeat the steps below, and after the first sbrk,
do 'b sbrk', then with the second 'p sbrk(4096)', step into the
routine line by line and report where it fails.  I'd like to see the
result of 

p get_reserved_heap_size ()

If the routine fails at the VirtualAlloc call, try modifying the call
by increasing the first argument by some amount, thereby deternining
whether a skip is needed.  Also would like the man page if any for
VirtualAlloc.

Take care,
