[tlbuild] Build progress with CYGWIN

[Rodrigo Medina]

Hi to everybody,
Report on the slow progress with CYGWIN.

I took the idea that it  was so from the replies to the follwing
message that was about building with HPux

    http://tug.org/pipermail/tlbuild/2008q3/000355.html

My compilation with graphite stopped exactly in the same
point of that message:
../include/graphite/GrFeature.h:110: error: syntax error before `(' token

In the next message
(http://tug.org/mailman/htdig/tlbuild/2008q2/000179.html)

2) About the SWAP problem included the following in XeTeXswap.h


#ifdef XETEX_MAC
#include "sfnt.h" /* for the 'fixed' typedef */
static inline fixed
SWAP(fixed p)
{
        return (fixed)SWAP32((UInt32)p);
}
#endif
/*BEGIN NEW CODE FOR CYGWIN */
#ifdef U_CYGWIN
#include "sfnt.h" /* for the 'fixed' typedef */
static inline fixed
SWAP(fixed p)
{
        return (fixed)SWAP32((UInt32)p);
}
#endif
/*END OF NEW CODE FOR CYGWIN */
static inline UInt16
SWAP(UInt16 p)
{
        return SWAP16(p);
}

3) About the library  libsicudata.a.
In deed the problem was with the file 
texlive-20080816-source/libs/icu-xetex/config/mh-cygwin
in which the name of the files are changed for buiding icu
but those changes are not propagated to xetex.
.
.
.
# Change the stubnames so that poorly working FAT disks and installation
program
s can work.
# This is also for backwards compatibility.
DATA_STUBNAME = dt
I18N_STUBNAME = in
.
.
.
I just commented out both instructions and the obstacle was overcome.
But few steps ahead a new obstacle appeared, just in the linking of
xetex.exe.  I think it is due to the same file mh-cygwin. Perhaps the
 easiest thing is to look at the source of icu for cygwin and copy the
 right file.

-----------------------------------------------------------

I suspect that the problem is due to the fact that libraries built were
static instead of dynamic. But I am an ignorant on dll's.
