I used the default flags, i.e. "-g -O2". So, the binaries will have
debug info, but will also be optimised.

FWIW, the complete configure command is:

./configure --with-proj-share=/usr/share/proj --with-cxx --with-motif
	--with-freetype --with-nls --with-readline
	--with-freetype-includes=/usr/include/freetype2 --with-postgres
	--with-tcltk-includes=/usr/local/include
	--with-tcltk-libs=/usr/local/lib

Both require GDAL, which requires a load of stuff; in this case:

glynn at WXP:~ $ cygcheck /usr/local/bin/cyggdal-1.dll 
C:/cygwin/usr/local/bin/cyggdal-1.dll
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\KERNEL32.dll
      C:\WINDOWS\system32\RPCRT4.dll
  C:\cygwin\bin\cygjasper-1-701-1.dll
    C:\cygwin\bin\cygjpeg-62.dll
  C:\cygwin\bin\cygpng12.dll
    C:\cygwin\bin\cygz.dll
  C:\cygwin\bin\cygpq.dll
    C:\cygwin\bin\cygcrypt-0.dll
    C:\cygwin\bin\cygcrypto-0.9.8.dll
    C:\cygwin\bin\cygintl-3.dll
      C:\cygwin\bin\cygiconv-2.dll
    C:\cygwin\bin\cygssl-0.9.8.dll
  C:\cygwin\bin\cygtiff-5.dll

For a sample program:

glynn at WXP:~ $ cygcheck /usr/local/grass-6.2.1/bin/g.proj
C:/cygwin/usr/local/grass-6.2.1/bin/g.proj
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\KERNEL32.dll
      C:\WINDOWS\system32\RPCRT4.dll
  C:\cygwin\bin\cygproj-0.dll
  C:\cygwin\usr\local\bin\cyggdal-1.dll
    C:\cygwin\bin\cygjasper-1-701-1.dll
      C:\cygwin\bin\cygjpeg-62.dll
    C:\cygwin\bin\cygpng12.dll
      C:\cygwin\bin\cygz.dll
    C:\cygwin\bin\cygpq.dll
      C:\cygwin\bin\cygcrypt-0.dll
      C:\cygwin\bin\cygcrypto-0.9.8.dll
      C:\cygwin\bin\cygintl-3.dll
        C:\cygwin\bin\cygiconv-2.dll
      C:\cygwin\bin\cygssl-0.9.8.dll
    C:\cygwin\bin\cygtiff-5.dll
  C:\cygwin\usr\local\grass-6.2.1\lib\libgrass_gis.6.2.1.dll
    C:\cygwin\bin\cygintl-8.dll
    C:\cygwin\usr\local\grass-6.2.1\lib\libgrass_datetime.6.2.1.dll
  C:\cygwin\usr\local\grass-6.2.1\lib\libgrass_gproj.6.2.1.dll

IOW, everything GDAL needs, plus cygproj-0.dll and cygintl-8.dll.

IMAGERYLIB requires GMATHLIB, which requires FFTW.

Actually, the first one is correct, although the only libgis functions
which the gmath library uses are the standard utilities (G_malloc,
G_fatal_error etc), which will get pulled in anyhow.

That figures. It would be nice if it told you that, or which ones were
missing.
